Audrina Patridge says it isn't difficult seeing her ex, Justin Bobby, lock lips with foe Kristin Cavallari on "The Hills."
"At the end of the day, it's a show," Patridge, 24, told Usmagazine.com Thursday at MTV's Los Premios in Los Angeles Thursday. "It's entertainment. And you can't take anything serious on that show."

She and Cavallari, 22, clashed on the sixth season premiere because Cavallari pursued Bobby.
Asked if she and Cavallari have since ended their feud, Patridge told Us, "I don't know. I really don't know how it's going to play out. We still have three weeks of filming - and that's it."

"I'm an adult now, and I don't need all the petty drama and drinking and fighting," Patridge, who just split from Aussie BMX racer Corey Bohan, recently told Maxim. "I've done that, and I'm ready to move on."
