Moulin Rouge star Nicole Kidman has been seen kissing Liz Hurley's ex, Steve Bing, reports FemaleFirst.

The 'friends', as they claim to be, were seen together in the Beverley Hills Hotel this weekend, where, a witness says "They were kissing. It wasn't a little peck. It was an open-mouthed lip-lock." A waiter there says that this is not the first time the celebrities have booked an intimate table.

The couple have been seen together several times, though apparently on this occasion they tried to become invisible by blowing out the candle on their table.

A spokesperson for Kidman claims that the relationship is purely platonic.
