The hills served as a pioneer for its genre and delivered some of the most iconic – and dramatic – moments in the history of reality TV.
The MTV series, which aired from 2006 to 2010, aired as a spin-off from Laguna beach and followed Lauren Conrad when she moved from her small hometown to the big city of Los Angeles with her BFF Heidi Montag.
As they embark on their new adventure, the pair become instant friends with their neighbor Audrina Patridge. Viewers watched as the girls experienced the highs and lows of their twenties, with Lauren attending the Fashion Institute of Design & Merchandising and scoring an internship at Teen Vogue, where she befriended a fellow intern Whitney Port. Heidi, meanwhile, got a job in public relations at Bolthouse Productions and Audrina landed a gig at Quixote Studios.
The hills also focused on the trio’s love life as Lauren got back together with – and subsequently broke up with – ex Jason Wahler, while Audrina navigated her on-off romance with Justin Bobby Brescia. For her part, Heidi fell in love with boyfriend Spencer Pratt, which led to the “you know what you did” heard around the world — and the end of Lauren and Heidi’s friendship.
Fellow Laguna beach alum Kristen Cavallari eventually took the reins as Lauren after she left the show in season 5, and narrated until the final episode in 2010. A revival series, titled The hills: a new beginning, premiered and aired for two seasons. Although Kristen and Lauren were both missing from the gang, the show did feature the return of Heidi, Spencer, Whitney, Brody Jenner, Stephanie Pratt and more.
