Lady Gaga showed who is queen of the stage during her catwalk debut at Thierry Mugler's Fall/Winter 2011 ready-to-wear show.

Granted, a catwalk isn't truly a stage, but the pop star treated it like one. She strutted and posed like a seasoned model - to the extent that one journalist remarked that she was better than the real models, who had difficulty channelling the bad girl vibes they were supposed to at Mugler's show.

Bad girl vibes? Piece of cake for Lady Gaga who has had plenty of experience in her music videos.

The star, who was the fashion show's music director, also premiered her new song "Government Hooker" on the catwalk.
