Pop star Lady Gaga showed off her cheeky side at a gig by flashing her derriere at the crowd. The 26-year-old performed at Twickenham Stadium here Saturday night for the first date on the British leg of her Born This Way Ball tour. She performed by bending over at the front of the stage, lifting her white T-shirt, and showing off her backside and skimpy underwear, reports contactmusic.com.

Gaga's cheeky stunt was not the only highpoint during the concert. She also unveiled a new song about late British royal Diana, Princess of Wales, titled “Princess D.I.E”
