Kate Moss has been caught kissing a woman – but only for a charity auction.

It came as a surprise to guests at the exclusive London event, however, as an intimate moment had been won by a man – tycoon Philip Green. Despite having paid £60,000 for the pleasure, he did the decent thing and passed it on to the next highest bidder.

The lucky recipient was Jemima Khan, Hugh Grant's girlfriend. Moss brushed her hair aside and dived in for a full-on passionate embrace.

"We thought it was going to be a kiss on the cheek," a guest told the Evening Standard. "It lasted just over 60 seconds. A few people were shocked but everyone was laughing after."

The auction – for the Hoping Foundation for young Palestinian refugees – raised more than £200,000 in total.
