Kristin Cavallari has only been back on MTV for a few months, and she’s already pushed Audrina Patridge into crazytown by gallivanting around with not one, but two of Audrina’s exes. First, she set her sights on Justin-Bobby Brescia and now she’s dating Tal Cooperman, co-owner of DCMA Collective clothing. While her affair with Justin-Bobby was a storyline for the show, Kristin has been cozying up to Tal of her own accord. According to a source, “It’s brand new. They’re having a lot of fun enjoying getting to know each other better. It’s not for the show. They hit if off and have been hanging out off-camera.” Sorry, Audrina. Looks like another boy has gone to the dark side. [The Hollywood Gossip]

What’s up with starlets boyfriend shopping in other girls’ closets? Is it just that they have the same taste and run in the same circles—or do they do it on purpose? We’ve found a few other culprits who are guilty of stealing multiple ex-boyfriends from another woman.

Lately, there’s been a rash of Hollywood starlets’ homes getting robbed. In February, a pair of burglars broke in to Audrina Patridge‘s house, and took off with several bags full of her clothes and accessories. In May, a thief rifled through Rachel Bilson‘s closet and took clothes, shoes, handbags, and jewelry. Then, in late August, Lindsay Lohan’s home was burglarized while she was out of town. Her security cameras caught three people—a man and two women swathed in scarves—in her driveway. Paris Hilton and Hayden Panettiere, who live within a few miles of these other ladies, also had similar robberies in the past year. But the LAPD seems to have this under control. They’ve arrested a suspect who they believe committed the Audrina and Lindsay burglaries, though they’re not sure if he’s connected to the other break-ins. His name is Nicholas Prugo. He’s 18 and is currently being held on $20K bail. How long do you think it will be before he squeals on his partners in (fashion) crime?

Hungry? Audrina Patridge of “The Hills” must be, cause that girl is skinnnnnny. And you know what people whose fame depends on them being thin do when they get hungry? They go to Carl’s Jr. for a Teriyaki Six Dollar Burger! Wait, that can’t be right…I heard they ate Styrofoam and pretended cigarettes were an all-you-can-eat buffet of smoke? Either way, Audrina donned a tiny gold bikini in Malibu for the latest Carl’s Jr. ad. She was psyched. “I had an absolute blast shooting,” she told People. “When I pulled up, I was literally salivating looking at all the rows and rows of perfect burgers waiting for me!” You’d be salivating too if you hadn’t eaten since high school.
