Big Mistake

Sarah Larson allegedly cheated on George Clooney.

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.

Alright, maybe cheating on George wasn't a big mistake cause they split for other reasons. Maybe he never knew, just like men rarely do.

Women are the best cheaters ever. We're thorough, we're slick. We come up with better excuses than 'I'm having a late day at work, I'll be at home a few hours later.' We say we're going for a mani and pedi instead, then tell ya we need money to pay the pool boy, but spend your funds on designer purses and pay for other things with bjs. At least that's how I think I'd get away with it.
