Later that year, Patridge competed on the eleventh season of the American version of Dancing with the Stars, and finished in seventh place. In 2011, she was commissioned her own television series, Audrina, which documented the lives of her and her immediate family. However, the series proved unsuccessful ratings and was canceled after airing only one season. Patridge entered the film industry with starring positions in the horror film Sorority Row (2009) and Direct-to-DVD film, Into the Blue 2: The Reef (2011). She was additionally featured as a supporting character in Honey 2 (2011) and Scary Movie 5 (2013), though her scenes were ultimately removed from the latter film.

Audrina Cathleen Patridge was born May 9, 1985, in Los Angeles, California, the daughter of Lynn (née Clelland) and Mark Patridge. She is of English, Belgian, Italian, Polish, and German ancestry, and has three younger siblings: Casey (born 1986), who is 14 months her junior, Mark (born 1988), and Samantha (born 1995). Patridge grew up in Yorba Linda, California.
In 2006, MTV developed the reality television series The Hills as the spin-off of Laguna Beach: The Real Orange County. It originally chronicled the lives of Lauren Conrad, who appeared on its predecessor, her housemate Heidi Montag, and friends Whitney Port and Patridge. During production of the first season, producers cast her in a position with Quixote Studios. The following season, Patridge was cast with Epic Records. Later in the season, Montag ended her friendship with Patridge after suspecting that she was involved with her boyfriend Spencer Pratt, though the women later reconciled. After Montag moved in with Pratt, Patridge and Lo Bosworth later became roommates with Conrad. During the third season, Patridge resumed an on-again/off-again relationship with boyfriend Justin Brescia, who Bosworth jokingly nicknamed "Justin Bobby". Their turbulent relationship carried through each subsequent season.
On May 28, 2009, she confirmed during an interview on On Air with Ryan Seacrest that she was leaving The Hills to star in her own reality program documenting her life outside The Hills. Her final episode of the series was supposed to be on December 1, 2009. However, she later signed on for the series' sixth (and final) season while her new series, produced by Mark Burnett, set to air on MTV in mid-2010, was put on hold due to The Hills. Patridge appeared in more episodes of The Hills than any other cast member.

In March 2008, nude pictures of Patridge were published online. "They were taken when I was just out of high school and beginning to model," Patridge has explained. "I was naïve, overly trusting of people, and inexperienced."

In August 2008, Patridge purchased a house in Los Angeles' Hollywood Dell neighborhood. On February 22, 2009, Patridge's home was burgled by two members of the Bling Ring. She appeared in an ad for PETA, encouraging people to adopt rather than buy pets.
Patridge appeared in Carl's Jr. commercials during 2009, 2010, and 2012. She refuted rumors that she would play the part based on her former Hills co-star Lauren Conrad in the film version of L.A. Candy based on the book by Conrad.
During a live press conference on August 31, 2010, Patridge was confirmed to be a contestant on the eleventh season of ABC's Dancing with the Stars. Her professional partner was Tony Dovolani.

In January 2011, she signed on to star in the YOBI.tv "Dream Maker" webseries. Following the end of her career in reality TV, Patridge continued to pursue acting, and was cast in a part in Scary Movie 5; however her scenes were cut from the finished film due to the scene being too risqué for the PG-13 movie.
