June 7, 2008 -- IT sounds like Audrina Patridge has had enough of Lauren Conrad's controlling ways. "The Hills" star, known for her sweet nature, has grown so uncomfortable around Conrad that they no longer speak, and Patridge won't stay at the guest house behind Conrad's home as she did during the show. "She hasn't officially moved out yet, but she stays with different people. It's grown so bad between them she doesn't want to be there," said one insider. "If your star starts to burn brighter than Lauren's, there's going to be trouble." Conrad was recently quoted as saying she and Patridge are "still friends." At a recent event for the newly relaunched Dodge Challenger, Patridge was overheard telling Michelle Trachtenberg how she's still looking at apartments. The two also dished on guys and raced each other on the speedway where Rob Lowe, Luke Wilson, Chace Crawford, Snoop Dogg and Carmen Electra cheered them on.
