New York, August 28 (ANI): George Clooney's ex-girlfriend Sarah Larson is said to have gone from a "hero to a zero" in her choice of dates, with sources in Las Vegas saying that she is going around with minor-league promoter Joey Vanas.

The sources have revealed that Larson was at a preview of Lavo in the Palazzo Saturday night with her new man, and that Vanas kept his hand on her leg all night as they sat in a booth with Lavo owners Noah Tepperberg and Jason Strauss and Vegas showman Jeff Beacher.

They even said that Larson and Clooney broke up earlier this summer because they had little in common, and because the former insisted on getting breast implants, reports the New York Post.

The sources also said that while Larson, a former cocktail waitress, was trying to kick- start a modeling career, she "came to Vegas for a weekend and cheated on him (Clooney)" with a media mogul.

According to them, before splitting from Larson, Clooney helped promote her new career, and she got a spread in Harper's Bazaar and a few runway gigs at LA Fashion Week. (ANI)
