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.
The Paparazzi singer took to the stage to sing Venus and started her show wearing a long floaty white dress, but apparently at the end of her performance she was COMPLETELY starkers. Yup, Lady G flashed her bum at the crowd by dropping her dress.
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!"
Club owner Jeremy Joseph also took to Twitter, unable to contain his excitement. He said: "I've just woken up, had this really odd dream that I was on stage at G-A-Y with a naked Lady GaGa."
Another of Jeremy's tweets said: "How incredible is @ladygaga, the hardest secret I've had to keep, sooooo happy, quadruple wow."
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.
