Next week marks the return of MTV's The Hills, but it's bringing back more than what we expected. We all know that Kristin Cavallari's going to join the crew to stir up some chaos. However, we weren't quite sure of the extent.
On the new trailer for the upcoming season of The Hills, the others have been warned about the nasty Cavallari. "Lauren basically told us she's a man eater. She's a boyfriend stealer," Audrina Patridge tells everyone upon the newcomer's arrival. No wonder she'll never quite be BFFs with Kristin.
Still, Cavallari told MTV News that she seems to get along pretty well with everyone on the show. She also loves playing the bad girl who messes with people's lives, particularly because she'll be remembered more for it.
"I'm friends with everyone -- except for Audrina," she said. She's also amused at how she's going to be portrayed on The Hills. "Honestly, I think it's fun to play the bad girl, and no one remembers the nice girl, you know?"
Even Stephanie Pratt refers to her as trouble on on the trailer, "She's like a disease you can't get rid of. She's the girl who's going to stab us all in the back, and she doesn't care. ... How can one person turn all of our lives upside down?"
Other drama this season will bring involves Speidi arguing about having babies. Heidi wants all the responsibilities of being a wife, but Spencer just can't see why. He confides to Stephanie that he wouldn't dare have a kid, even after a hundred years.
There's also the problem of Spencer's sister-in-law Holly Montag, who probably has to get help for her drinking. "I think Holly might need to go to rehab," Heidi admits. "I want to help however we can."
Below, you can watch the trailer for new episodes of MTV's The Hills, premiering on September 29.
