Letting her wardrobe do the talking, Lady Gaga exited the Roundhouse in London sporting a peculiar frock on Sunday night (September 1).

The “Edge of Glory” gal donned a flamboyant white bubble dress following her unforgettable performance at the iTunes Festival, and her fans were thrilled with the display.

Meanwhile, Gaga’s deejay friend Brendan Sullivan has just released a new book called “Rivington Was Ours: Lady Gaga, the Lower East Side, and the Prime of Our Lives,” in which he chronicles meeting her back in 2006 and the subsequent wild ride.

Sullivan writes, “We’d go out every night, eight nights a week, if we could. She would match me for drinks toe-to-toe. People loved her as a dancer. When she was dancing on stage, they were like, ‘Wow, who’s that?’ And that was the beginning of Lady Gaga.”
