Lady GaGa was left red-faced after slipping and falling on her backside on the opening night of her The Monster Ball Tour in Canada.
The pop star was performing her song Teeth in Montreal on Friday (27Nov09) when she lost her footing in her stiletto ankle boots and fell over on stage.
GaGa's male dancers swiftly helped her back onto her feet and she shrugged off the mishap to complete the song and dance routine.
The Poker Face singer isn't the only star to trip up on stage recently - Jennifer Lopez nursed a bruised butt after the American Music Awards in Los Angeles on 22 November (09) when a dance move went awry.
