Sarah Larson has infuriated her famous boyfriend George Clooney by sharing his deepest secrets - including his exotic tastes for kinky sex games.

The 28-year-old was working as cocktail waitress and go-go dancer in Las Vegas before she started dating George, and it seems her time in the City of Sin has left her with a carefree attitude about sex.

'She isn't shy about discussing sex or what she and George get up to in the bedroom,' one of Sarah's friends says. 'She says he's the best lover she's ever had but also the kinkiest!

'The first time I spoke to her about it I guess I was curious to know what George Clooney was like in bed, but I was shocked by the answers. She said he is really into role playing and loves outrageous games.

'She also said he encourages her to be a bad girl for him - he loves the naughty side to her personality!'

But 46-year-old George was furious to discover Sarah has been openly discussing their love-life and risking alienating his more straitlaced fans with details of his secret fetishes.

'The next time I spoke to her about it I was teasing her about our last conversation and how wild their love-life was, but she took it as an invitation to share even more personal stuff,' the friend says. 'The other stuff was crazy to the point where

I wished I'd never asked about it in the first place!'

Ironically, Sarah's indiscreet revelations about her sex life with George could cost her the chance to remain the object of his affections. He's extremely private, especially where his love-life is concerned.

'George would hate the fact Sarah has been talking about his most personal desires,' one of his friends says. 'If he finds out about this I wouldn't be surprised to see him put her on the first plane back to Las Vegas.

'George has a tremendous image both with the public and in the industry and he can't have the whole world knowing the most intimate details of his love-life!'

But it's not just sexual secrets Sarah is sharing. The small-town girl has also told those closest to her that she ‘knows she and George won't end up happily ever after' and 'he tells me all the time we'll never marry.'

Marriage always looked a long shot, but now he's been left red-faced by her loose tongue, those close to the actor say she'll be lucky to still be on his arm at Christmas!
