Audrina Patridge won't say if she's back on with her ex, Australian BMX rider Corey Bohan. (The two were recently spotted smooching in Las Vegas.)

"I've been having fun with him," she told Usmagazine.com Tuesday at the Reebok EasyTone Footwear Celebration in L.A. "I don't want to jinx anything, so I'm not going to label it! He's one of the nicest, sweetest guys I've ever met. We'll see."
