Could Sarah Larsen's newly-enhanced breasts have prompted her split from George Clooney?

The former Vegas cocktail waitress underwent breast augmentation in May this year, and a U.S magazine suggests that the actor just isn't a boob man.

"George really didn't want her to get the boob job. She asked George if she could do her recovery at his house and he agreed," an insider tells In Touch Weekly.

As for the break-up itself, it appears that George let the press do his dirty work for him. What a gent!

The source adds, "They had a huge fight and he left the house. Sarah read in the media that they'd broken up and freaked out because George hadn't told her anything.

"He had to explain himself because she'd found out with the rest of the world."

At least Sarah still has her new curves to fall back on.

A friend says, "She likes her new body so much that she would consider posing for Playboy. Now that she's famous, she'd never go back to cocktailing."

Famous? That might be stretching it a bit...
