The American sitcom Two and a Half Men, created and executive produced by Chuck Lorre and Lee Aronsohn, premiered on CBS on September 22, 2003. The show initially centers on six characters: brothers Charlie and Alan Harper; Jake Harper, the dimwitted son of Alan and his first ex-wife; Judith Harper-Melnick, Alan's first ex-wife, Herb's current wife, and Jake and Millie's mother; Rose, one of Charlie's previous one night stands who continuously stalks him; and last of all, Evelyn Harper, Charlie and Alan's rich, five time widowed, bisexual mother, and Jake's grandmother. In season two, the Harper's sharp-tongued housekeeper, Berta, joins the main cast after playing a major recurring role in the first season. In season nine, the show is revamped when Charlie falls in front of a train and dies. Walden Schmidt replaces him as the new owner of Charlie's house, a recently divorced internet billionaire. In season eleven, Jake moves to Japan and is downgraded to a recurring role, so to replace "the half-man", Charlie's long-lost-daughter moves into the beach house after looking for her late father.
Over time, several supporting characters have been promoted to starring roles: Berta (season 1 recurring; season 2-present regular), Charlie and Alan's (and later Walden's) sharp-tongued housekeeper; Kandi (season 3 recurring; season 4 regular; season 10 guest), one of Charlie's former one night stands, and later on, Alan's second ex-wife; Chelsea (season 6 recurring; season 7 regular; season 9 guest), Charlie's second most notable love interest (after Rose), and ex-fiancée; Walden Schmidt (season 9-present), an internet billionaire who buys Charlie's beach house after his death; last of all, Charlie's daughter (season 11-present), Charlie's illegitimate daughter from a one night stand twenty years before. The show also features numerous supporting characters, each of whom plays a prominent role in a small group of episodes.

- Kathy Bates appeared as Charlie Harper in a single episode in season 9.
Charles Francis "Charlie" Harper (Charlie Sheen, (seasons 1–8); Kathy Bates, (season 9)) is the series' original central character. He is a womanizing bachelor who tended to bully his younger brother Alan, whom he loved, although he would have never admitted it, and usually took pleasure in any dismay or trouble he runs into. He was the opposite of Alan: lucky, brave, and wealthy. He gave his nephew, Jake, advice (much of which is not age-appropriate), but the two increasingly traded barbs as well. Charlie is killed sometime between seasons 8 and 9 as he is hit by a train and it is revealed that he had proposed to Rose before his death. While Alan is in the hospital, Charlie's ghost appears to him (It is implied that this is due to a hallucinogenic reaction due to the medication Alan was on.) and explains that his spirit now lives on in Hell forced to live eternally in a woman's body (Kathy Bates) as punishment for his womanizing behavior during his lifetime. He acts as his brother's spirit guide, though he later confessed that he really could not care less about what he does. Before returning to the afterlife, Charlie tries to reveal himself to Jake but it fails. Charlie has not made another appearance since but he is sporadically mentioned.
Dr. Alan Jerome Harper (Jon Cryer, seasons 1–present), Charlie's younger brother, who is conscientious but continually stricken with bad luck and teased by Charlie, Berta and Judith. He and his ex-wife, Judith are Jake's parents, and Alan is possibly the biological father of Judith's second child, a daughter named Millie Melnick. After losing his house to Judith in the divorce, he moves in with Charlie. He is generally a kind and patient man, but seems to have an attraction to women who treat him poorly, which may stem from the non-nurturing relationship he had with his and Charlie's mother. In the season 4 episode, "Repeated Blows to his Unformed Head", it is revealed that Alan has a pregnancy fetish, which he says is due to Judith only varying from her sexless marriage policy while pregnant with Jake. Also, in the Season 6 episode, She'll Still Be Dead at Halftime, he confesses that he likes feet (see foot fetish). In the season 3 finale, Alan marries a twenty-two-year-old dumbbell named Kandi who was one of Charlie's former girlfriends. After Charlie had canceled his wedding with Mia, Alan and Kandi got married instead. Although in the season 4 premiere, four months after the marriage Kandi throws Alan out of her condo and divorces Alan which leads him to paying alimony to two ex-wives.
In season six, Alan starts his first serious relationship since his second divorce. Alan starts dating his receptionist, Melissa. The relationship gets serious when Melissa has Alan move in with her and her mother, but their happiness is short lived when Melissa's mother gets Alan high on brownies and seduces him. Melissa walks in on them, but Alan is too high to explain what happened. Melissa breaks up with Alan and kicks him out. In the season six finale, while Judith is giving birth to what is possibly Alan's daughter, Alan and Melissa meet up and have sex in a closet, ultimately getting back together. Their relationship goes into season seven where Melissa wants to move into the beach house with Alan, Charlie, and Chelsea. Alan is happy to live with Melissa at first, but eventually Melissa and Chelsea start taking over the house, resulting in Alan and Charlie staying at a hotel. Alan and Charlie call Evelyn to fix everything. Evelyn tells Chelsea about Melissa's short lived romance resulting in the girls getting into a fight, and Melissa moving out. Alan and Melissa are now forced to have sex in their car since Melissa won't let Alan see her mother at her house, and Melissa doesn't want to see Chelsea at Alan's house. Melissa tells Alan to get his own house, so Alan steals the keys to a house Evelyn is selling, and lies to Melissa, saying that it's his. When Alan and Melissa get caught, they sneak out the window, but the cops find Alan in nothing but his briefs and when he tries to explain what happened, he turns to Melissa only to find she's gone.
Towards the end of season seven, Alan starts dating Lyndsey McElroy, the mother of Jake's friend, Eldridge, and Judith's neighbor. Alan and Lyndsey date for the last three episodes of the seventh season, and their relationship goes into season eight. Lyndsey and Alan get serious and Lyndsey has Alan move in with her. After moving in, Alan goes to the liquor store where he runs into his ex-girlfriend, Melissa. Alan and Melissa start an affair, but the affair is short lived when he decides to move on from Melissa and continue his relationship with Lyndsey. At Lyndsey's house, Alan smokes a pipe which Lynsey finds sexy. Lyndsey takes Alan upstairs to have sex, but Alan didn't realize he put the pipe down while it was still lit, resulting him burning down Lyndsey's house. Lyndsey stays mad at Alan for most of the next episode, but when she finally forgives him, her ex-husband Chris steps in and makes up with Lyndsey, leaving Alan brokenhearted and alone again. Several episodes later, Lyndsey breaks up with her ex-husband when she realizes she's lost feelings for him. Alan and Lyndsey get back together, and date for rest of the eighth season.
Alan is two years younger than Charlie. Prior to Two and a Half Men, Cryer and Sheen appeared together in the 1991 comedy Hot Shots! Cryer also won the 2009 Emmy Award for Best Supporting Actor in a Comedy Series. Alan stays at the house as Walden temporarily lets him after helping him with Bridget, but Walden later insists that Alan stay with him permanently when Alan, with Bridget's help, saves him from Courtney (Jenny McCarthy), a femme fatale who previously had a relationship with Charlie, and was out to get Walden's money. Alan and Walden became best friends after that. This friendship eventually earned Alan a position as a board member of Walden's company and his name on the deed of the beach house. Walden also renamed his company "Walden Loves Alan Enterprises" in honor of his best friend. As of season 9, Cryer is the only actor on the show to appear in every episode of the series. Alan continues his romance with Lyndsey during season nine, only for her to break up with him again after she finds out about all of his lies.
While Walden is dating Zoey, Zoey sees right through Alan and knows that he is sponging off Walden. Walden and Zoey go on a date one night and reluctantly take Alan with them. At dinner, Alan sees his ex-girlfriend Lyndsey. Alan and Lyndsey reconcile at the end of the episode. Alan dates Lyndsey throughout the rest of season nine, and reveals to Jake that he and Lyndsey have no intention of getting married.
In season ten, Walden starts to grow tired of Alan living with him, and begins to get more annoyed. Alan continues to sponge off of Walden for money, and Walden continuously asks when he is moving out. Alan and Lyndsey continue their relationship, but Lyndsey starts to fantasize other people when seeing Alan. In "Something My Gynecologist Said", Lyndsey asks Alan for a commitment since her gynecologist asked her out. Alan is reluctant, resulting in Lyndsey breaking up with Alan again. That night, Alan goes over to Lyndsey's house and proposes to her. Alan tells her that as soon as he has enough money, he'll put a deposit down on a ring.
Not too long after getting engaged, Alan gets an email from his second ex-wife, Kandi who's in town and wants to get coffee. Kandi tries getting back together with Alan, but he refuses due to his relationship with Lyndsey. Towards the end of season ten, Lyndsey breaks up with Alan after she feels like all the spark in their relationship is gone.
Jacob David "Jake" Harper (Angus T. Jones, seasons 1–10) is the son of Alan and Judith, while E.G. Daily provided the singing voice for Jake in the opening and closing theme songs of seasons 1–8, and the first two episodes of season 9. He spends most of his free time playing video games, eating, watching television, playing the guitar, sleeping, and getting high with his best friend Eldridge. He is also an excellent poker player and a fairly good cook, but is very uneducated and stubborn, which coupled with his excessive flatulence, is a frequent theme of jokes about him. Despite his apparent lack of intelligence, he is sometimes very observant. He clearly loves his father and uncle, but is often aggressive towards them. He blamed his parents divorce on Alan for many years and continually disrespected him for that reason and it was only after he enlisted that he realized that Judith had more to do with the divorce than he'd originally thought. Jake's style, personality and attitude changes as the series progresses, from a more adorable, little-boy charm in the first season to a caustic teenager in later seasons. After Charlie's death, Jake at first does not show any emotion but it is later revealed that, like Alan, he severely misses him and still grieves his passing (though not as bad as Alan). He proceeds to tell his father that the most important thing Charlie taught him was that when he is his uncle's age he wants to be married and have a family, because Charlie seemed very lonely. Despite his young age, he has proven himself to be charming enough to seduce older women (as evidenced in seasons 9 and 10). Jake and Eldridge decide to join the Army following their high school graduation. Jake forms a friendship with Walden, who buys the beach house, and has such an impact on his life he tells Walden that he would name his child with his then girlfriend Tammy, Walden Harper.
Walden Schmidt (Ashton Kutcher, seasons 9–present) is a billionaire internet entrepreneur who has recently been divorced and was suicidal when Alan first met him. When Charlie dies and leaves the house to Alan, Alan puts the house on the market because he is unable to make payments on the three mortgages. Guest stars John Stamos, Jenna Elfman and Thomas Gibson view the house but do not buy it. While Alan is speaking to Charlie's ashes and trying to decide where to spread them, Walden appears from nowhere on the back deck, scaring Alan and causing him to drop the ashes across the living room floor. Once inside, he reveals that he was trying to drown himself in the ocean, having been recently divorced from his wife Bridget, portrayed by Judy Greer. He and Alan bond at Pavlov's bar, where he tells Alan that he made his $1.3 billion fortune by selling his website to Microsoft. After picking up two women and bringing them back to the house, where he sleeps with them, he decides to buy the house.
His wife describes him as emotionally immature, which upsets him, so, with Alan's help, he returns to his mansion to confront his wife in the hope of reconciling. However, he is sent away after being treated for an electric shock that he received while climbing the front gates of the mansion. Walden gets a second chance when Bridget later decides that she had been too harsh and that he deserves a chance to prove he is not as childish as he was; this chance is quickly ruined by a food fight between Walden and a little girl in the middle of Soup Plantation. Walden eventually invites Alan and Jake to continue living at the house they have been living in for 8 years with him as Walden wants someone around he can trust, and they became best friends. He used to walk around the house naked, and is often barefoot. He drives a Fisker Karma, and asks Evelyn to remodel the house using solar power and wind power.
Walden starts dating a British woman named Zoey (Sophie Winkleman) whom he met at the supermarket. Bridget later comes wanting Walden back but he declines her wanting Zoey instead. She later is seen stalking him where she runs into Rose who says she can help make Walden suffer. Bridget reluctantly goes with her. Walden was introduced with a beard and long, greasy hair, but when he started to get serious with Zoey, he decided to cut his hair and shave. Walden has also matured a great deal by spending time with Alan and dating Zoey. Though he still considers Alan his best friend, he eventually became aware that Alan is a freeloader and now understands what Charlie had to put up with. In season ten, Walden proposes to Zoey but she turns him down, and leaves him for another man. He starts dating Charlie's former stalker Rose, but Zoey tries to reconcile with Walden, telling him she made a mistake. When Walden tells Rose that they're going to have to break up. Rose acts like she is okay with it at first, but after leaving, she sends two ferrets to attack Walden. Rose goes to Zoey's apartment wearing a pregnancy harness and tells Zoey that Walden got her pregnant. Zoey breaks up with Walden for good once more without letting him explain himself.
Later in the season, Walden takes the alias of Sam Wilson and pretends to be a regular, average guy so he can find someone who isn't after his money. Walden meets Kate (Brooke D'Orsay), and tells her that he lives with billionaire, Alan Harper. Kate invites Walden to be her roommate, and they ultimately start dating. Walden keeps the lie going for several episodes until he wants to help Kate set up a fashion line of clothes she designed. Walden put 100,000 dollars in Alan's bank account so he can invest in Kate. After Kate goes to New York, Walden decides to confess who he really is. Walden meets Kate in New York and tells her the truth. Kate breaks up with Walden, but forgives him when she realizes he helped make her dream of being a fashion designer come true. Kate and Walden don't get back together, due to Kate staying in New York. On Valentine's Day, Walden and Kate meet up and sleep together. When they realize they can't get back together due to conflicting schedules, the couple agree to see other people.
Jenny (Amber Tamblyn, season 11-present) is the long lost, illegitimate daughter of Charlie Harper. An aspiring actress and proud lesbian, Jenny first appears in the premiere episode of season 11, in which she comes to Malibu hoping to reconnect with her dad. After warming up to her, Walden and Alan invite her to move in after she reveals she has nowhere to go. Though she exhibits many of Charlie's personality traits (particularly, his sarcasm, alcoholism and womanizing), Jenny is considerably much nicer and down-to-earth than he was. Thus far, she has formed good relationships with her surviving relatives, Walden, Berta and Walden's friend Barry (Clark Duke). She and Jake have never met thus far, but she does know he exists and would like to meet him. In "Welcome Home, Jake" she meets Barry for the first time, mistaking him for Jake. She happily gives him a hug only to be disgusted when she discovers the truth. She eventually takes a liking to Barry and the two become the best of friends. Though it is apparent that Walden is attracted to her, he believes she has no drive or ambition. Fearing she may turn into "another Alan", he tries to be a positive role model for her. Jenny considered Walden the greatest father figure she'd ever had.
Berta (Conchata Ferrell, season 1 recurring; season 2-present regular). Although the sharp-tongued housekeeper's manner may be viewed as sarcastic, Alan and Charlie still treat her with a great deal of respect, partly out of fear, and it is clear that the household cannot function properly without her. Berta has tried her best not to allow the overwhelming stress of her job to get to her head: when Alan (a generally tidy person) moved in, she quit and Charlie was so upset that Alan had to personally beg her to return and promised that he would do his own cleaning. However, the fact that Jake's bedroom could be confused with a dump (at various times including dead fish in the closet, food left-overs in his toy box, and nasal mucus under the bed), that his toilet seat is frequently sprayed with urine, and that his underwear is filthy often leads to anger on her part. Her favorite line after a mini disaster occurs in the house is, "I ain't cleaning that up." During the Kutcher years of the show her role on the series was increased. Season 11 was the first time she'd appeared in every single episode of a season.
Berta has a sister named Daisy, played by Camryn Manheim, with whom she does not get along. She also has three daughters and a number of granddaughters, whom she admits are "sleazy and easy" and whom she sometimes brings along to work. A notable example was when she brought her teenage granddaughter Prudence, played by Megan Fox. Berta has two ex-husbands, her first marriage lasted fifteen years while her second marriage was a drunken escapade in Las Vegas. Berta divorced her second husband in Reno and often refers to the marriage as "one hell of a weekend." She has served time in prison and worked as a prison barber. She uses, and makes references to, drugs (legal and otherwise); it is hinted that she has enjoyed many a joint during work hours, and can produce a perfect one given the opportunity. She takes anxiolytics (Valium especially) in her coffee to reduce her violent tendencies. She was a groupie with the Grateful Dead, and implied that she has had a lesbian experience while there. While it had been hinted several times prior to Charlie's death that he had changed his will so she'd inherit the beach house instead of Alan, that turned out not to be true, although Berta still was set to move out because the house had mortgages attached that Alan had no chance of paying.
Berta often calls Alan "Zippy." She, along with Alan and Evelyn, are portrayed as the only people saddened over Charlie's death. She considered him to be the best boss she ever had at that point. After Walden buys the house, he asks her to remain there as a live-in housekeeper. She agrees but mainly because she was extremely attracted to Walden, and would often make discreet advances at him. This living arrangement is short-lived when she finds out that Alan will be moving back in, only this becomes more likely when Walden sees Berta invite a piggish house guest over earlier. She never thought she could work for anyone besides Charlie, but admits to Walden that he is instead the greatest boss she ever had, making Charlie second best. Berta hardly ever shows any signs of attraction to Walden after season nine.
Evelyn Harper (Holland Taylor) is Charlie and Alan's mother and Jake and Jenny's grandmother. In the first season, she is 58 years old. She expresses a superficial fondness for her sons and grandson, but she rarely lives up to her self-perceived notion of being a devoted and misunderstood matriarch. Her sons and grandson generally return the favor and go out of their way to avoid interacting with her on most occasions. Her wide-ranging sex life is a recurring gag throughout the series. In addition to Teddy who was not actually "Courtney"'s father, Evelyn has been sexually involved with several parents of her sons' lovers, including Rose's father, Gloria's mother, Gloria's presumed father, Gloria's likely biological father (i.e., the boys' father, Frank Harper), and Lyndsey's mother. She also bedded Charlie's ex-girlfriend Jill who had become Bill. Evelyn has been widowed five times, her fifth marriage being the shortest as he died an hour after saying their vows.
The family frequently refers to her as "the devil" (or, as Charlie put it, "unholy mother of us"), and Charlie has her number on speed-dial in his cell phone as "666." Once, she showed up at the door in a black cloak with carrying a scythe. When Alan asked who it was, Charlie responded "It's Death," to which Alan replied, "Hi, mom!" It has been implied on one occasion that she literally is a witch (who is dreaded and feared by other witches). Wealthy, with a luxurious house, she has been married numerous times and sells real estate. When Charlie died, surprisingly, she was distraught over his death. At his funeral, however, she continuously mentions her intention to sell his house while Alan was giving his eulogy. Her relationship with Alan has somewhat gotten better since Charlie's passing, as she has acknowledged that he is not just her second-born son, he is now the only son she has left, as well. When Alan almost died from a heart attack, she feared for his life, because not only did she not want to lose another child, her "good son" was already deceased.
Two years after Charlie's death, she finally meets her long lost granddaughter Jenny. Surprisingly, Evelyn embraces her newfound grandchild and completely disowns Jake. In the eleventh season she maries for the sixth time, this time to her much older lover Marty Pepper.
She rarely appeared during season nine, but was prominent in the last few episodes of the season. Despite still credited and billed as a main character, Evelyn only made one appearance in the tenth season.
Judith Harper-Melnick (Marin Hinkle) is Alan's cheating, vindictive, cold hearted, self-absorbed, and humorless ex-wife. She seems to despise Alan and takes any chance to humiliate him. She was the first woman Alan ever slept with, but their marriage was cold: according to her, the only time she was ever happy being sexual was when she was pregnant with Jake. In the pilot, she lied to him about realizing she was homosexual as an excuse to end the marriage, and in subsequent episode he caught her picking up multiple men. She made no secret of living luxuriously with Alan's alimony, seeing as she has not held a job since she divorced him. She has since remarried to Dr. Herbert "Herb" Melnick (Ryan Stiles), Jake's pediatrician, a union that brought joy to Alan because it meant he no longer had to pay alimony.
In season six, she threw Herb out of the house and briefly reunited with Alan before reconciling with Herb, and it was later revealed she was pregnant with a daughter, whom she eventually named Millie. Alan hoped he was the father, but Judith said she would kill him if he revealed that he slept with her, and after she gave birth in the sixth season finale, the child's parentage remained uncertain, as Judith was with both Herb and Alan around the time Millie was conceived. Jake and Berta describe Millie as looking nothing like Judith or Herb but more like a girl version of Alan, implying Alan is the probable biological father.
In seasons seven and nine, Judith made very few appearances but was featured in almost every episode in season eight. She was not seen since the season nine finale until towards the end of season ten, with only being briefly mentioned for most of the season. In the episode "Run Steven Staven, Run!", Judith's absence is finally explained when Herb mentions that Judith left him when he cheated on her with his receptionist. However in the 19th episode of season ten, she reappears after a long absence when Herb starts to go crazy. Walden and Alan call her to go to Herb's hotel room and take him back.
She returned in the season eleven episode "Cab Fare and A Bottle of Penicillin", when Alan showed up at her house just to talk about old times and after a night of drinking they end up engaged. However in the end, Judith ends the engagement after Walden explains to her that Alan had proposed to Lindsey the same night he proposed to her (however he did not explain that she didn't accept Alan's proposal as she is now engaged to Larry). Angered by this, she kicks Alan in the groin and leaves.
Rose (Melanie Lynskey, seasons 1–2 regular; season 3–5, 8, 10-present recurring; 6–7, 9 guest) is the Harpers' wealthy neighbor and Charlie's stalker and after his death, she finds new love and a stalker victim in Walden. She was one of Charlie's one-night stands who won't allow him to forget about her as he does all his other sexual conquests. Rose acknowledges that she is "boundary challenged", while Charlie and Alan refer to her as Charlie's stalker. In the pilot, she told Alan that she sneaks into Charlie's room while he's asleep and tries on his underwear. Usually uninvited, she enters and exits Charlie's house by climbing onto the backyard deck, rather than using the front door. She has been caught by Charlie and Alan as she watched them sleeping on several occasions. While credited among the main cast in CBS press releases in Season 3–4, she was credited as a recurring star in on-screen credits. After season 4, she left for London and appeared on the show only rarely. She later returns to Malibu in Season 5, though no longer living next door to Charlie, hence her less frequent appearances. She claims she was sent away from England after "an incident at Buckingham Palace." In Season 6, she became friends with Charlie's fiancee Chelsea and went on a blind date with Alan; the two began dating before Rose evinced the same jealousy and possessiveness towards Alan that she had applied towards Charlie, right down to gluing things to his genitals. Although she is somewhat mentally unhinged and obsessed with Charlie, Rose expressed that she "has an undergraduate degree from Princeton University (which she completed in 2 years) and a master's degree in behavioral psychology from Stanford University." Throughout the series, Rose has applied her knowledge of interpersonal communication towards the various situations that arise. Her family is involved in banking and oil, making them, and implicitly her, extremely wealthy. Martin Sheen, who is Charlie Sheen's real-life father, made a guest-appearance on the show as Rose's equally-disturbed father who similarly obsessed over Evelyn after sleeping with her once. Rose also has five ferrets, all named "Charlie," as was revealed in Season 2's "The Salmon Under My Sweater." Her only appearance in Season 7 was in "Gumby with a Pokey" when Charlie begins to hallucinate (after taking medicinal marijuana). Women in his past interrogate why he mistreated them, then he goes out to the deck to discover Rose; unlike the other women, Rose is really there. She made multiple appearances in Season 8, after staging her wedding, which makes Charlie realize he probably loves her. In the last episode of Season 8, Charlie leaves for Paris with her. In Season 9, Rose reveals that she and Charlie got engaged in Paris. It is implied she may have had something to do with Charlie's death after she returned to their Paris hotel to find him showering with another woman. She reappears again at the end of "What A Lovely Landing Strip" catching Walden's ex-wife Bridget spying on Walden and his new girlfriend, she then tells her that she can help her in making Walden suffer. She makes a brief cameo through archive footage in a flashback montage in the episode "Oh Look, Al-Qaeda!". She returns in Season 10's "That's Not What They Call It In Amsterdam" now dating Walden, much to Alan's dismay. The relationship gets serious but is short lived when Walden reconciles with Zoey. However, Rose gets revenge by telling Zoey that she is pregnant with Walden's baby. Walden ends up without Zoey or Rose. Rose continues to stalk Walden as well as the Harpers, despite Charlie's death. Rose returns in "Advantage: Fat, Flying, Baby", at the end where it's discovered that Rose is Walden's girlfriend's new investor for her fashion line. The character has been described as a sociopath although she has a warm and friendly exterior.
Kandi Harper (April Bowlby, season 3 recurring; season 4 regular; season 10 guest) is Alan's second ex-wife. Initially Charlie's gorgeous but dim-witted girlfriend until Charlie broke it off with her so he could date Mia. When Judith (who later became Kandi's confidante) initially tried to end Kandi's relationship with Alan, Kandi's mother Mandi (Gail O'Grady), who also had a brief fling with Charlie during that time, made sure the couple were dating again. During this time Judith briefly dated Kandi's father Andi (Kevin Sorbo) leading an interesting joke Jake told his father about the possibility Kandi could be his stepmother, stepsister and stepcousin all at once. Kandi and Alan had a superficial relationship based mostly on sex, but they eventually wed in Las Vegas, where they also won half a million dollars. After only four months of marriage, and spending nearly all of their winnings, Kandi kicked Alan out of their condominium, which was later revealed to be because Alan did not want to have another child with her. Kandi is soon offered a role (as a sexy forensics expert) on a CSI-type television series, entitled Stiffs. At the same time, Alan sees that Jake is practically grown up and he returns to Kandi to agree to have a baby with her. However, moments before they try to conceive, Kandi finally signs the divorce papers, to ensure that Alan would not have any claim on her new-found television lucre, and disappears from Alan's life. Bowlby had also appeared as another character named Kimber earlier on in the series prior to playing Kandi. Kandi was not been seen or mentioned from the fifth season onwards, although Alan, Charlie and Jake have all mentioned that Alan "has been married twice." While credited among the main cast during the fourth season, CBS press releases billed her as a recurring character. In the tenth season, after many years of being unmentioned, Alan received an email from Kandi and the two met, revealing that she had become a successful television star. Kandi wanted to win Alan back, to the point of saying he was the "best lover she ever had", though he was in a committed relationship with Lyndsey McElroy. Kandi and Lyndsey later had sex when Kandi went to her home to convince her nothing had happened between her and Alan. The two women agree to never tell Alan about it.
Chelsea (Jennifer Taylor, season 6 recurring; season 7 regular, season 9 guest) is Charlie's girlfriend for most of season six, who has moved into his house by the season's end. Formerly a one-night stand, Chelsea seems to be one of the few women out of Charlie's countless relationships that has caused him to try to make positive changes in his debaucherous lifestyle. She became close friends with Alan, something Charlie enjoyed because Alan could take her to museums and foreign films (activities that Charlie cannot stand). In the seventh season premiere, Charlie finally decides to let go of Mia and commit to Chelsea. As the season progresses they plan to marry but, after Chelsea becomes attracted to Alan's lawyer and Charlie vomits on a baby, Chelsea postpones the wedding. In Season 7 Charlie and Chelsea make several attempts to reconcile, most recently following her breakup with Brad (the man Chelsea left Charlie for). Chelsea tried to reunite with Charlie, but was thwarted due to her best friend, Gail (Tricia Helfer), sleeping with him. Jake later gives Chelsea a necklace that Charlie got her for her birthday and she goes outside to see him but when she got there, Charlie was in trouble with the police for rear ending a police car, with a suspended license. Jake was driving at the beginning of this episode, but when the police came after them in a cop car, Jake and Charlie switched seats, causing Charlie to lose his license. While credited among the main cast as Jennifer Taylor during the seventh season, CBS press releases bill her as a recurring character. At Charlie's funeral, she says he gave her chlamydia.

Ava Pierce (Talyan Wright, seasons 9–10) portrays Zoey's young daughter from her marriage to Nigel. Well mannered and intelligent, Ava adored Walden, and is 108th in line to the throne. Ava invites Walden to her birthday during season ten, despite her mother having broken up with him.
Billy Stanhope (Patton Oswalt, season 9-10), Walden's business partner and frenemy. Walden and Billy have a love and hate relationship, and even though they don't realize it, they're probably best friends. In season nine, after years of not speaking to one another, Walden and Billy start their business back up again. In Billy's next appearance, he reveals that he has been seeing Walden's ex-wife, Bridgit. Walden and Billy sell their company in season ten for $1 billion. In mid season ten, Bridget breaks up with Billy, resulting in Walden, Alan, Billy, and Herb having a guy's night drinking and complaining about women.
Bridget Schmidt (Judy Greer, season 9-10), the ex-wife of Walden Schmidt. She initiated the divorce proceedings because she felt Walden would never become a mature adult, but after the divorce was ready to be finalized she decided she loved him anew and wanted him back. Unfortunately, Walden decided to sign the divorce papers and continue his nascent relationship with Zoey, leading Bridget to become violently unhinged and to fall into the orbit of a returned-from-Paris Rose. Bridgit later started dating Walden's business partner Billy at then end of season nine but she left him in "Run Steven Staven". In Season 4, Greer portrayed the role of Myra Melnick the sister of Herb Melnick, Judith's fiance/husband, in the episodes "Smooth as a Ken Doll" and "Aunt Myra Doesn't Pee a Lot", during which she had a brief swing with Charlie before she returned home to her fiancee, whose existence came as a shock to Charlie.
Celeste (Tinashe Kachingwe, seasons 6–7), Jake's ex-girlfriend, and main love interest of seasons six and seven. Jake first meets Celeste when she and her dad, Jerome, move in next door to Charlie. Jake and Celeste secretly date at first because her father is over protective, but he eventually gives the couple his blessing. Celeste shows to be controlling over Jake, but he doesn't seem to notice. In season seven, Celeste spends Christmas with her mother, so Charlie convinces Jake to cheat on Celeste. Celeste stops by Charlie's house to give Jake his Christmas present, but when she sees that he is cheating on her, she breaks up with him. Jake tries to get Celeste back in the following episode, but has no luck.
Courtney Leopold/Sylvia Fishman
Courtney Leopold/Sylvia Fishman (Jenny McCarthy, seasons 5, 8–9), Charlie's girlfriend for a multi-episode thread. Charlie falls for "Courtney", whom he believes is the daughter of Evelyn's fiancée, and lends her a substantial amount of money and proposes shortly before they are to become step-siblings. She also forced Charlie to buy a car from her so the secret of their relationship would not get out to her father and Evelyn. Charlie is heart-broken to learn that she is actually a con artist named Sylvia Fishman, but he retains feelings for her, telling her that he will "wait" for her (to get out of prison). She reappears in Season 8's "Ow, Ow, Don't Stop" after being released from prison, and Charlie immediately falls for her again, even professing his love for her. The two break up two episodes later in "Chocolate Diddlers or My Puppy's Dead" when they realize they have simply lost their feelings for one another and, in an extremely rare case for Charlie, they part mutually and on good terms. In the season 9 episode "Nine Magic Fingers", Courtney starts dating Walden, but their relationship is short-lived as Alan and Bridget successfully convince Walden that Courtney is a con artist.
Dr. Linda Freeman
Dr. Linda Freeman (Jane Lynch, seasons 1, 3–9, 11), initially as Jake's, then as Charlie's and occasionally Alan's adept, incisive but money-hungry psychiatrist. Often when Charlie or Alan are just getting to the root of their problem, Dr. Freeman notes that the area is interesting, "but, unfortunately, we're out of time". She prides herself as a guesser and is quite sarcastic, especially with Charlie. A recurring gag is her frequent over-billing, once charging Charlie a full hour's fee ($200) for 5 minutes of consultation, and on another occasion while treating Alan for insomnia she billed him for an entire hour after he slept for 40 minutes of the session pointing out that she was awake. In one episode, she tells Charlie to open up and not hold anything back as her hourly fee comes to "$7 a minute". During her sessions with Jake, Dr. Freeman displays a rather quirky demeanor and is noted for her use of a cow hand puppet. She later has a session with Walden in season 9. It is implied that she (like her actress) is gay, as after Walden hugs her, she remarks "Hmph. Maybe I'm not gay." 
Eldridge McElroy (Graham Patrick Martin, seasons 7–9), Jake's best friend whose mother Lyndsey (Courtney Thorne-Smith) dated Alan. Eldridge is a dim-witted drummer and somewhat of a trouble maker. In his first appearance at the end of season 7, he and Jake get into trouble after sneaking off to the beach with "a few" beers. While Jake and Eldridge are friends, the relationship between their parents briefly causes some friction in their friendship but remain friends and decide to join the Army following their high school graduation. He is never seen or mentioned again after season 9.
Gordon (J.D. Walsh, seasons 1–4, 6–8), a pizza delivery driver who idolized Charlie. During the third season he has a brief relationship with Rose, who forces him to dress like Charlie and yell the latter's name during sex. After their break-up, he disappears from the show, but returned in season six, again delivering pizzas. He revealed how he became a millionaire on the stock market, got married and subsequently divorced and then lost all his money to his ex-wife, forcing him to return to pizza delivery. He looked up to Charlie, often calling him a genius and always addressing him as "Mr. Harper" rather than the more familiar "Charlie". Charlie invariably orders pizza from Gordon's pizzeria for him to deliver, irrespective of the distance; including when subletting his own live-in girlfriend Chelsea's old apartment in the San Fernando Valley, and when camped out with Alan et al. in Lyndsey's burned-out house twenty miles from the beach. Gordon is unaware that Alan briefly dated Rose after his own relationship with her. Since he has not appeared since Season 8, it remains unknown if he knows that Charlie has passed away.
Dr. Herbert "Herb" Melnick (Ryan Stiles, season 2, 4-10) portrays Judith's goofy, train-hobbyist, pediatrician second husband and Jake's stepfather. He first appeared as Judith's date in Season 2's "Enjoy Those Garlic Balls," but due to an inconsistency in the storyline, he was initially referred to as "Greg Melnick." Not particularly happily married to uptight Judith, he is laid-back and gets along with the Harper brothers, whose lifestyles he appears to envy at times—such as Charlie's partying and the fact that Alan was married to Kandi and later dates neighborhood MILF (and former soft-core porn actress) Lyndsey McElroy. He and the other men in Judith's neighborhood similarly idolize Lyndsey's ex-husband Chris for repeatedly seducing the babysitter. He has stated that he likes spending time with the Harpers, and called Charlie "a little loosie-goosie with the liquor and the ladies, but all-in-all a good fella" (which did not impress Judith). In the Season 6 finale, Judith gives birth to their daughter, whom they name Millie Melnick. However, Herb does not know that Judith had a brief affair with Alan around the time Millie was conceived, and remains in the dark about the fact that Alan could possibly be Millie's biological father. Single for most of his life, Herb's hobbies center on gardening, his large model train layout, and "accidentally" bumping into Lyndsey every morning. Sexually, he is particularly adept at cunnilingus. In season ten, Herb has an affair with his receptionist and Judith leaves him; he keeps the house (Alan's former house). After she leaves him Alan lives with him briefly after he and Walden have a fight, but tries to keep Alan as he is lonely without Judith. He begins to party out of control to get over Judith, so Walden and Alan call Judith to try and calm him down. Herb and Judith then reluctantly get back together and Herb returns to normalcy.
Herb does not make a single appearance in Season 11. In the episode, "Cab Fare and A Bottle of Pencillin", it is implied that he and Judith have separated for a third time and have possibly divorced, as he is nowhere to be seen at his and Judith's house.
Judge Linda Harris
Judge Linda Harris (Ming-Na Wen, season 5), Charlie's main love interest of the fifth season. Charlie and Linda met through Alan, and his girlfriend Donna. Charlie and Linda's first date doesn't go as planned, but Charlie gets himself arrested in order to see Linda at court. Linda agrees to give Charlie another chance. Linda and Charlie start to get serious, but their relationship is in trouble when Charlie starts to see Rose's face on every woman he sees. Charlie flies to London to see Rose, but when he learns that Rose is ready to start a family, Charlies flees London and continues his relationship with Linda. Charlie learns that he is good with kids when he meets Linda's son, Brandon. Charlie makes Brandon a mix tape of kid's songs, and when Linda's ex-husband hears them, he offers Charlie a job as a kid's singer. When Linda is awarded as "Judge of the Year", she takes Charlie to a function that celebrates her. Evelyn accidentally gives Charlie the wrong pill that instead of calming him down, it makes him act crazy. After being humiliated at the function, Linda breaks up with Charlie.
Kate (Brooke D'Orsay, season 10-), Walden's ex-girlfriend and main love interest of season ten. Walden decides he wants to come up with a new persona so he can meet a girl who isn't after his money. Walden pretends to be the make believe Sam Wilson. Walden and Kate meet at the department store where she works. Walden (as "Sam") and Kate go on a few dates and Kate meets Alan, "Sam's" landlord and she hates him. Kate tells Walden that he can move in with her and he agrees. They also spend Christmas together. Walden has Alan invest in Kate's fashion line with Walden's money and Kate goes to New York to host her fashion show. Walden feels depressed with Kate gone and he gains a lot of weight. Alan helps Walden lose it and they fly to New York so Walden can tell Kate who he is. Kate gets furious and breaks up with him but later realizes that Walden helped her get her fashion show so she forgives him but they remain broken up since Kate has to stay in New York. Kate returns three episodes later and Walden spends Valentine's Day with her. They are forced to break up due to their busy schedules. It is revealed to the audience that Rose is Kate's new fashion line investor (Walden and Alan are ignorant of Rose's involvement, and Kate is unaware of Rose's connection to them and her psychosis).
Lyndsey McElroy (Courtney Thorne-Smith, season 7-present), Alan's on-again/off-again girlfriend, the mother of Jake's best friend, Eldridge (Graham Patrick Martin), and – to her extreme consternation – the daughter of Evelyn's lover, Jean (Georgia Engel). Years ago, she was featured in a soft-core porn movie, Cinnamon's Buns. She and Eldridge live in the San Fernando Valley, across the street from Judith, Herb, Jake, and Millie. She divorced her husband Chris after discovering his affair with their babysitter. Alan began dating Lyndsey at the end of season 7, and their relationship was initially kept a secret from their sons. They have since had several breakups and reunions. In the Season 9 episode "One False Move, Zimbabwe" Alan says Lyndsey is dating someone else, a fact later confirmed when he meets her very young (and rich, and handsome) boyfriend and is misled into thinking he could reunite with her. However, Lyndsey later breaks up with the boyfriend and tells Alan she wants to resume dating him; he is initially happy, then somewhat downcast when she explains that she had to work too hard to look sexy and cover up her bodily functions to keep the young guy, and she can forget about all that with Alan because he's not going to find anyone else. Alan later tells Jake that he and Lyndsey are dating but have absolutely no intention of getting married. They however get engaged in season ten episode "Something My Gynecologist Said". This does not deter Lyndsey from having sex with Alan's ex-wife Kandi in when Kandi attempts to reconcile with Alan. Sometime later, Lyndsey breaks up with Alan. In Season 11 however, it seems as though Alan and Lyndsey were never engaged as he planned on proposing to her but this time, she chooses another man.
Megan (Macey Cruthird, seasons 8–9), Jake's math tutor and brief girlfriend. Jake develops a crush on Megan in season eight, but she does not reciprocate the feelings. In season nine, Megan falls for Walden which makes Jake jealous. After realizing she has no chance with Walden, she settles for Jake and they start dating. When Alan is sent to a mental hospital, he has a nightmare that Jake gets Megan pregnant but in reality, Jake reveals that he and Megan never had sex, but he plans to that evening.
Melissa (Kelly Stables, seasons 6–8), Alan's receptionist who briefly dated Charlie before starting a relationship with Alan. She broke off the relationship after discovering Alan in bed with her mother (Alan was under the influence of marijuana, provided by Melissa's mother). The two reconcile and begin dating again, but Alan's cheapness and lack of a private area for them to make love causes a second breakup. She reappeared in Alan's life in the second episode of season 8 ("A Bottle of Wine and a Jackhammer"), complicating Alan's relationship with Lyndsey. Alan and she had a bad breakup and she violently forced Charlie to reveal Alan's location with Lyndsey, but she never showed up there, wasn't a factor in Alan and Lyndsey's breakup at the time, and has not been seen since. She was mentioned in "A Giant Cat Holding A Churro" when Alan was sharing his secrets with Lyndsey, saying he "cheated on her with an old girlfriend." 
Mia (Emmanuelle Vaugier, season 3 recurring, seasons 5–7, 9 guest), a ballet teacher whom Charlie Harper fell in love with during the third season. She got him to clean up his act by not drinking nor smoking as much, not wearing bowling shirts as well as not eating meat. However, he breaks up with her after he becomes fed up with the way she was trying to control his behavior. She then takes a job in New York. She returns towards the end of the third season when her dancing group comes to town, and she asks Charlie for his sperm so she can have a baby. He attempts but fails, and he then proposes marriage to her, in which she accepts. Initially, Alan was their wedding planner, however after a big blowout with Mia's parents, they agree to go to Las Vegas and elope. Just as they are about to be married, Mia implies that Alan and Jake will be moving out after they wed, and Charlie refuses to throw out his family. They break off the engagement and she leaves. Mia returns in the fifth season when Charlie sees that she is marrying another man, and he attempts to win her back, but her father punches him out. She returns again the sixth and seventh seasons after her divorce in hopes that Charlie will help her with a new-found singing career. She's a terrible singer. Charlie then has to choose between Mia and his then-fiancee Chelsea. After much consideration, Charlie chooses Chelsea and abandons Mia at the recording studio. Mia also makes a brief guest appearance in the ninth season première at Charlie's funeral.
Robin Schmidt (Mimi Rogers, season 9-present), the primatologist mother of Walden Schmidt. Robin is on the board of directors at Walden's company along with Walden, Bridget, and later Alan. Robin raised Walden from birth until he was four with a baby gorilla to study the differences of the growth between humans and monkeys. Walden spends Christmas in season nine with Robin. Robin is quite wealthy and has a good relationship with both Bridgit and Zoey. Robin teamed up with Bridgit to get Walden kicked off the board of directors because she felt he was using money irresponsibly. In season 11 she appeared at a fund-raiser with Linda Carter, and at the end of the episode it is implied she had a threesome with Jenny and Linda.
Teddy Leopold/Nathan Krunk
Teddy Leopold/Nathan Krunk (Robert Wagner, seasons 4–5), Evelyn's fiancee, thought to be the father of Courtney. He is later revealed to be Courtney's partner in a con game, moments before he marries Evelyn. Teddy first appears in the season four finale and maintains a recurring role half way through season five where he and Evelyn become engaged and married. On their wedding day, right after being married, Teddy is found with his pants down, dead on Charlie's bed. It appears Courtney wasn't his daughter but his partner; their real names were Nathan Krunk and Sylvia Fishman. Teddy is Evelyn's fifth deceased husband, although their marriage was not consummated before he widowed her. His catchphrase was, "terrific".
Zoey Hyde-Tottingham-Pierce (Sophie Winkleman, seasons 9–10), the British girlfriend of Walden Schmidt up until the second episode of season 10. She is more mature than Walden. She has a daughter in kindergarten and is divorced. She is a lawyer and has a slight disdain towards Alan and the French. In season ten episode "Ferrets Attack", Zoey attempts to reconcile with Walden but she finds out he has moved in with Rose. Walden leaves Rose for Zoey but Zoey no longer wants him as she is mad that he and Rose became serious. She has not been seen since and only briefly mentioned twice.
Marty Pepper (Carl Reiner, seasons 7-8, 11-), Evelyn's much older boyfriend, a retired TV Producer. Evelyn first invites him round to Charlie's house when she goes to visit.

He gives the boys advice on how to score with women, telling them to say to a woman that he will give her, her own sitcom. He reappeared in season 11 in multiple episodes. He meets Evelyn's newly found granddaughter but does not like her living with hem when Walden throws her out of his house as she is receiving all of Evelyn's attention, leaving no time for sex between them. He initially mistakes Evelyn inviting Jenny to stay as a sexual reason as he had never done a grandmother/grandchild combination before. He believes Walden and Alan to be gay together and at his wedding to Evelyn asks the minister to marry them. He put Walden and Alan in charge of his stag party, but it ends in disaster and he breaks of the engagement as he does not want to be tied down, but he eventually resumes the marriage and becomes Evelyn's sixth husband with Walden and Alan as his best men.
