It's official. After weeks of rumors circulating about "Laguna Beach" star Kristin Cavallari heading to "The Hills" and replacing Lauren Conrad, EW confirms that the 22-year-old will star on the MTV show's next season. In an interview with the actress, who is starring the upcoming DVD releases "Spring Breakdown" and "Van Wilder: Freshman Year," Cavallari doesn't pretend for a moment that the show is real and says she plans to shake things up.
"It's a TV show," she said. "I'm not going into it like, 'I'm going to make great friendships with these people.' It's work! And drama sells.
