Robbie Williams bared his bum and snogged a fan in a sensational display at the MTV Latin America Music Awards in Mexico last night (October 19).

The singer, who took home the Best International Pop Artist gong, was performing his appropriately named tune 'Rudebox' when he grabbed his crotch, exposed his nipples and then decided to drop his kegs.

With the crowd going wild at the sight of his not-at-all dimply derriere he then gabbed a fan in the front row of the audience and planted a smacker on her lips - and what started out as a (kind of) innocent peck soon turned into a full-on snog.

If that wasn't enough the singer then shocked the audience with a cheeky acceptance speech as he picked up his special TONGUE-shaped award - "Thank you I would like to place this on your clitoris," he beamed.

Blimey, good to see the Robster back to his ramped-up cheeky best.
