Clooney’s Former Flame Does Sundance

While she’s no longer dating a movie star, model and Reality TV contestant Sarah Larson is certainly enjoying the Sundance Film Festival.

Celebuzz spotted the 30-year-old George Clooney ex at the Las Vegas Hard Rock Hotel’s Smashtime party at the Hollywood Life House on Main Street last night.

“She was partying pretty hard,” said a source, “going wild at Hard Rock, drinking and dancing.”

Clooney and Larson split in May of last year, with initial reports saying 47-year-old George dumped the beauty (who managed a spread in Harper’s Bazaar under their relationship tenure).

Soon after the break-up, Larson was seen out and about with a former flame, a Las Vegas-based editor for 944 magazine named Ryan Doherty.

We can reveal the two are certainly still spending time.

“Sarah was grinding on Ryan all night, her legs wrapped around his waist, massaging the small of his back,” said the spy.

Also spotted at the Hollywood Life and Red Bull’s bash: Ashlee Simpson-Wentz ex Ryan Cabrera, Brittany Snow and Whitney Port’s City hottie Jay Lyon.
