Paris Hilton has sparked speculation that MySpace CEO Chris DeWolfe is her latest victim after the pair were spied “sucking face” at the Sundance Film Festival over the weekend.

“They were grinding each other on the dance floor forever, before lying together on a banquette,” says a New York Daily News spywitness. “Then the couple began sucking face hard. They left out the back door, with her hand in his pants pocket.”
