The Hills may be long over, but after rewatching the show I realized that Audrina Patridge was the worst friend to Lauren Conrad throughout the years the series was on. The Hills, a spin-off of Laguna Beach: The Real Orange County, followed Lauren after her tumultuous senior year at Laguna Beach High School and a semester-long stint at college in San Francisco. Realizing her true dream of working in fashion, Lauren and her friend Heidi Montag took on the big city with their new LA friend Audrina by their side. Living in the same apartment building, the show was a hit.
