Lady GaGa And Elton John Unleash 'Dirty' Grammy Performance - Photos

Lady GaGa stole the show as she was joined on stage by Sir Elton John at the Grammy Awards in Los Angeles last night.

The veteran entertainer accompanied the singer on piano, performing a hybrid of his own songs and  Lady GaGa's hits.

Dressed in a distressed suit, which was covered in dirt, Sir Elton smiled as the pair exchanged lyrics.

Lady GaGa's stage set had been designed to resemble a Fame Factory in honour of her debut album, 'The Fame'.

The performance capped a successful night for the singer, who also won two awards -  Best Dance Recording and Best Dance Album.
