Lady Gaga was in London today performing at the iTunes Music Festival where she debuted some new tracks off of her upcoming ARTPOP album. On the Red Carpet at the VMAs last week, Gaga mentioned this record’s existence and now it’s come to fruition. Above we have footage of Lady Gaga Too $hort and Twista performing/debuting the new single, despite the fact that T.I. wasn’t allowed to cross the pond. Below is the high quality audio of the single and we’ll update the post when the official CDQ comes out.
