Stephanie Lynn Pratt (born April 11, 1986) is an American television personality. In 2007, she came to prominence after being cast as a supporting position in the reality television series The Hills, which documented the personal and professional lives of Lauren Conrad, Heidi Montag, Audrina Patridge, and Whitney Port. In 2010, the series underwent several casting adjustments and saw Pratt become a primary cast member, joining Patridge, Lo Bosworth, and Kristin Cavallari.
2007–10: The Hills 
In 2007, Pratt joined the cast of The Hills during the third season, as Spencer's angry sister who confronted Lauren Conrad. She eventually apologized to Lauren and became one of her close friends, causing a rift between her and Spencer. The fourth season saw Pratt's role increased, with more emphasis placed on her personal life and her past drug abuse. During the fifth season, Stephanie worked with Lauren at Kelly Cutrone's People's Revolution, though Lauren ended Pratt's internship, per Cutrone's orders, due to poor performance. Conrad left the series after the first half of the season.
The second half of the season continued with Kristin Cavallari hired as the replacement narrator. Pratt and Cavallari began as rivals due to conflicts about Audrina Patridge's ex-boyfriend and a report linking Cavallari to drug use, though they would become friends during the following season. Pratt also became friends with Audrina and Lo Bosworth during the season.
Despite rumors of not returning after the fifth, Pratt returned and was featured as a main cast member in the sixth and final sesason. Stephanie talks of her DUI arrest, and her sibling rivalry with Spencer became more intense as his behavior became more erratic. Stephanie and the rest of the cast either did not mention Spencer or Heidi after the two were permanently axed from the series, or kept their comments focused on how no one knew what the couple were up to, and had avoided any recent contact with them. The Hills ended its series run on July 13, 2010.
Personal life 
Pratt is the younger sister of Spencer Pratt, and the sister-in-law of Heidi Montag (both of whom are on The Hills.) She has struggled with bulimia in the past due to the pressure to be thin stemming from appearing alongside very thin co-stars on the show.
Stephanie Pratt has stated in many public appearances that she has not seen her brother or his wife Heidi Montag in more than a year.
Stephanie Pratt remains close friends with her former Hills co-stars, Lauren Conrad and Lo Bosworth.
Legal troubles 
In a 2007 US Magazine interview, Pratt revealed previous substance abuse problems and discussed an incident in which she shoplifted $1,300 worth of merchandise from a Neiman Marcus in Honolulu in 2006, while working as a production assistant on ABC’s LOST.
On October 18, 2009, Pratt was arrested in Hollywood, California, on suspicion of drunk driving, and booked into jail in Van Nuys. She took two breathalyzer tests, first blowing 0.08, then blowing 0.09. The legal limit in California is 0.08. She was released several hours later after posting a $5,000 bail.
On August 4, 2012 Pratt's boyfriend, Line Snob app co-founder Julien Chabbott was arrested in New York City for driving over a police officer's foot, following Chabbot's attempts at avoiding a parking ticket. The incident was caught on camera and later uploaded to YouTube. In the video, Pratt is seen intervening and then driving Chabbott's Ferrari 458 away from the scene after the arrest.
