Audrina Patridge may play a scream queen in her new movie, Sorority Row, but there was nothing scary about the stunning strapless she wore to the flick's L.A. premiere. 'Drina, who recently described the film as "sexy," "suspenseful" and "super gory," looked completely at ease with her costars Rumer Willis and Jamie Chung.

"We actually all clicked and we became friends," the reality-turned-film star told PopSugar.com earlier this week. "Whereas on The Hills it’s kind of like you have to film with someone even if you don’t want to."
Like, say, Kristin Cavallari, whose flirtatious relationship with Audrina's ex-boyfriend, Justin Bobby, caused the normally staid Hills star to explode in the new Season 5.5 trailer.

"I mean, The Hills is fun," Audrina continued, "but on the movie it was a totally different group of girls. It was effortless, I have to say." And as for her rumered feud with K-Cav? "We’ll see what happens," she said mysteriously. "[W]e’re not done yet."
