Lady Gaga's cheeky flash

Lady Gaga showed off her cheeky side at a gig by flashing her butt at the crowd.

The Poker Face hitmaker took to the stage at Twickenham Stadium near London on Saturday night (08Sep12) for the first date on the British leg of her Born This Way Ball tour.

And she gave the audience of 55,000 fans more than they bargained for by bending over at the front of the stage, lifting her white T-shirt, and showing off her backside and skimpy underwear.

Gaga's cheeky stunt was not the only moment of controversy during the concert - she also unveiled a new song about late British royal Diana, Princess of Wales titled Princess D.I.E.
