Lady GaGa stripped down to a black bra and stockings and donned a moustache for her latest odd performance at a fabled sex club in Berlin, Germany.

The provocative pop superstar was promoting her upcoming album Artpop at the infamous Berghain venue - and she was dressed appropriately for the saucy show on Thursday night (24Oct13).

The Applause singer hit the stage for 50 competition winners.

Her latest showcase came hours after she was spotted out and about in the city sporting a bizarre blonde headpiece which covered her entire face.
