Alyson Lee Hannigan (born March 24, 1974) is an American actress. She is known for her roles as Willow Rosenberg in the television series Buffy the Vampire Slayer (1997–2003), Lily Aldrin on the CBS sitcom How I Met Your Mother (2005–present) and Michelle Flaherty in the American Pie film series (1999–2012).
Early life 
Hannigan was born in Washington, D.C. She is the only child of Emilie (Posner) Haas, a real estate agent, and Al Hannigan, a truck driver. Her father is of Irish descent and her mother is Jewish. Her parents divorced when she was two and she was raised mostly by her mother in Atlanta, Georgia.
At age four, Hannigan began appearing in commercials. She moved to Hollywood at age 11. Living with her mother and attending North Hollywood High School, she successfully auditioned for agents while visiting her father in Santa Barbara. After attending North Hollywood High School, she attended California State University, Northridge where she earned a degree in psychology.
Hannigan's first major film role was in My Stepmother Is an Alien, a science fiction comedy released in 1988; one of her co-stars in the film was actor Seth Green, who would later join her in the regular cast of Buffy as her on-screen boyfriend. Then in 1989, her first regular role on a TV series came when she was cast in the short-lived ABC sitcom Free Spirit.
In 1997, Hannigan was cast to play Willow Rosenberg, Buffy Summers' best friend, on the television series Buffy the Vampire Slayer. The show became a success, and Hannigan gained recognition, subsequently appearing in several notable films aimed at teenage audiences, including American Pie, American Pie 2, Boys and Girls and American Wedding. She also had a guest spot on the Buffy spin-off, Angel, reprising her role of Willow in a few episodes (including most notably "Orpheus," during the fourth season of Angel and the seventh season of Buffy), but none after Buffy finished production.
In 2005, Hannigan returned to starring in a regular television series, appearing in the hit comedy How I Met Your Mother as Lily, and also playing a recurring guest role on Veronica Mars as Trina Echolls.
Hannigan joined forces with Emily Deschanel, Jaime King, Minka Kelly, and Katharine McPhee in a "video slumber party" featured on FunnyorDie.com to promote regular breast cancer screenings for the organization Stand Up 2 Cancer.
Personal life 
Hannigan married fellow Buffy the Vampire Slayer actor Alexis Denisof at Two Bunch Palms Resort in Desert Hot Springs, California, on October 11, 2003. The couple have two daughters, Satyana Marie Denisof, born March 24, 2009, and Keeva Jane Denisof, born May 23, 2012. Hannigan and her husband are godparents to Joss Whedon's son, Arden.
On February 13, 2013, Hannigan was granted a temporary restraining order against New Hampshire resident John Hobbs after he began sending her threatening and obsessive messages via internet, wishing to meet and possibly kill her. On March 6 2013, the restraining order was extended to last for a further 3 years.
