Talk about a case of beauty and the beast. George Clooney's ex and DWTS alum Elisabetta Canalis is rumored to be dating Jackass star Steve-O.

According to Radar Online, paparazzi caught the two stars kissing in Los Angeles. Canalis couldn't resist Steve-O's humor after mutual friends introduced the pair, a source told Radar.

"Steve makes Elisabetta laugh, and that's her weakness," the source said. "That was her favorite thing about George Clooney -- he was always cracking her up and playing practical jokes on her."

The source also told the gossip site that for now, the lovebirds are just "hanging out and hooking up."

Canalis and Clooney ended their 18-month romance last June.
