Hills star Audrina Patridge has reportedly said it’s “laughable” that her rival Kristin Cavallari is dating her ex-boyfriend.

Reports claim that Cavallari, 22, is dating her ex-boyfriend Tal Cooperman, who is the co-owner of the DCMA Collective clothing line.

A source said to Usmagazine.com: “Audrina thinks it’s laughable. Tal and Kristin have gone out a few times now, but it’s nothing serious. Tal and Audrina never officially dated and are still friends.”

Cavallari previously dated another of Patridge’s ex-boyfriends, Justin Bobby, and the source added: “Why does she continue to chase Audrina’s sloppy seconds?”
