Sarah Larson, George Clooney's latest girlfriend, has been caught in raunchy photos scandal. Some photos of the former cocktail waitress, showing her acting all slutty in Vegas last year, have been all over the net.

Star Magazine obtained the photos, claimed to be taken at the Palms resort in July 2007 just a month after Larson first met the movie hunk. One of the raunchy pics shows Larson "wearing a short dress and has her legs wrapped around a man holding her up against a wall in the middle of a crowded Vegas nightclub," the publication claimed.

Another picture, elsewhere, showed Larson "wearing a bikini at a huge, outdoor pool party at the Hard Rock Hotel & Casino, kneeling on all fours with her backside in the air as she licks the cover of a magazine lying on the ground."

In addition to both pics, Larson was also shown in other snap rolling around on the floor as she wrestles a bikini-clad blonde.

"That's our Sarah!" a source close to Larson told Star. "She's not shy in the slightest. She loves hamming it up and is never embarrassed. That's the Sarah everyone in Vegas remembers, not the girl dressed in Valentino minding her manners for the cameras with George at the Oscars!"

The source went on adding, "Sarah looks like she totally belongs, walking down the red carpet on George's arm. She's even been described as having a successful runway and print modeling career. But until recently, her modeling career consisted mostly of being paid by promoters for clubs, magazines and radio stations to attend special events in sexy outfits and party with her wild girlfriends! Sarah is outgoing and fun and loves to drink. She likes to get wasted when she goes out - but hey, that's what Vegas is all about!"
