Audrina Cathleen Patridge (born May 9, 1985) is an American television personality, television presenter, actress, and model. In 2006, she rose to prominence after being cast in the reality television series The Hills, which chronicled the personal and professional lives of Patridge and friends Lauren Conrad, Heidi Montag, and Whitney Port. During its production, she was cast in positions with Quixote Studios and Epic Records. As the series progressed, Patridge resumed an on-again/off-again relationship with boyfriend Justin Brescia. Consequentially, it became a central focus of the series, and was carried through each subsequent season.

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. In 2014 and 2015, Patridge hosted NBC's late-night travel show 1st Look.
