Reformed party girl Tara Reid got more than she bargained for when she joined Akon onstage at a Sundance Film Festival bash on Monday night - she found herself getting sexed up by the singer and one of his entourage.

The actress started gyrating with the singer onstage at the Blender Sessions party when they were joined by a very energetic dancer. Reid then found herself being tossed in the air by the sexually-charged performers as they simulated a sex act with the star.

A partygoer says, "Tara looked to be enjoying herself. It was like some weird, clothed sex ritual."
