Lady Gaga took to the stage at London's G-A-Y last night to perform a new song from her ArtPop album. But that wasn't all the star revealed - if the rumours are true, Gaga got a little bit naked on stage.
Gaga opted for white hair and VERY pale make-up, perhaps opting for a little dose of Halloween action.
Afterwards, she tweeted: "Had an amazing night tonight at G-A-Y in London, after all these years you continue to inspire me. Can't wait for X-Factor tomorrow night!"
And he also claimed to have been groped by the singer onstage.
But how far did Lady G strip? Thankfully comedian Matt Lucas reported back with all the details...
Just saw Lady Gaga do a surprise set at G-A-Y. She got her arse out & showed her vagina. All agreed it was impressive but we're staying gay.
