Paris was reportedly seen pinning down MySpace CEO Chris DeWolfe at the Tao bar at the Sundance Lift in Utah.

One clubber claimed: 'They were grinding each other on the dance floor forever, before lying together on a banquette. Then the couple began sucking face hard. They left out the back door, with her hand in his pants pocket.'

But an insider at MySpace downplayed the claims, telling: 'This is what happens when altitude affects your brain. They're just having fun.'
