Lady Gaga did more than simply bare her bottom and flash a bit of flesh at fans during an unannounced show at a London gay club on Saturday night (26Oct13) - she disrobed and left the stage completely naked. The provocative pop star took to the stage in a flowing white petticoat-style dress and long blonde wig at nightclub Heaven to perform her upcoming single, Venus, live for the first time. And she made sure her gay fans in attendance had plenty to talk about when she slipped out of her stage costume and walked off naked with her arms in the air. The gig came just days after Gaga stripped down to a black bra and stockings and donned a moustache for an odd performance at a fabled sex club in Berlin, Germany. And it's not the first time she has stripped off recently - she bared all for the Jeff Koons cover art of her new album, ARTPOP, and she also disrobed for a promo video with performance artist Marina Abramovic this summer (13).
