Season three of The Hills may still be going on, but we've got a clue about what's going down in recently confirmed season four: Audrina Patridge will be shooting her first movie! "I go next week to film it," she told Ryan Seacrest yesterday. "I don't know how much I'm allowed to say!" She'll play "the girlfriend of this cocky guy who think he's the S...and I kind of have him wrapped around my fingers," she says, adding "It's cool because on The Hills, I don't have that." (Uh, that's for sure!) And Audrina's stoked to act -- and not just in the reality TV way. "[The movie is] giving me the chance to show people [what I can do]," she says. "This is why I moved to LA."

Audrina also chatted about the tension shown between her and Lauren Conrad because of Lauren "Lo" Bosworth on Monday's eppie of The Hills."It's not like, 'Boo hoo, feel bad for Audrina,'" she says. Sometimes on the show, things come across differently." Also discussed was Audrina's revived friendship with Heidi Montag and the effect it had on Lauren and Audrina's relationship. "Lauren is very big on you-know-what-you-did," she says. "I looked at the whole situation. It's none of my business. I am the neutral one on the show -- I can't fight other people's battles."
