Sarah Larson cheated on The Clooney?

Larson was at a preview of Lavo in the Palazzo Saturday night with her new man, minor-league promoter Joey Vanas. Vanas kept his hand on Larson’s leg all night as they sat in a booth with Lavo owners Noah Tepperberg and Jason Strauss and Vegas showman Jeff Beacher, drinking vodka.
Larson seems to have a roving eye. Sin City sources say that while the former cocktail waitress, who’s trying to kick- start a modeling career, was dating Clooney, she “came to Vegas for a weekend and cheated on him” with a media mogul.
Larson and Clooney broke up earlier this summer. Sources said it was because they had little in common and because Larson insisted on getting breast implants. But, ever the gentleman, Clooney helped promote her new career before he dumped her, and she got a spread in Harper’s Bazaar and a few runway gigs at LA Fashion Week.
