The 27-year old singer, who was dressed in a white ethereal smock-dress when she started performing her new ARTPOP single, Venus, lifted up her smock and pulled down her knickers to flash her private parts at the nightclub, the Mirror reported.
Gaga later took off her dress completely and flaunted her naked body to the crowd before walking off the stage.
