VIDEO : Heidi Montag Dishes On 'The Hills' Ten Years Later

A decade after Lauren Conrad packed up her convertible and headed off to Hollywood, the promise of revolutionary reality television nestled in her back pocket, the cast and crew of The Hills are now sharing their sides to those. The cameras happened to be at the right place at the right time, you could say. As Montag described to Us Weekly, "real reactions within scripted moments." controversial moment of the series arrived when Conrad cut ties with her on-screen right-hand woman, Heidi Montag, after Conrad thought she and boyfriend Spencer Pratt were spreading rumors of a sex tape between Conrad and Wahler. Cue the "You know what you did!" moment. "To me, those were the best scenes?the really real ones," Conrad told the magazine. "We're not, you know, sitting in a cute café discussing who said what the night before. They were always the hardest to shoot, but I felt like that was when people could really relate to us." "From season 3 on, everything with Spencer was completely scripted," Montag told the magazine. He wasn't the only one on the show who saw dollar signs. "The money was the reason I did it," Cavallari, the series' protagonist for seasons five and six, told the magazine. "Producers gave me an offer I couldn't refuse. I'm glad I went back to [reality TV] because this time I looked at it strictly as a job, and I knew the character they wanted me to play."
