Lady Gaga cancelled 22 shows on her Born This Way tour earlier this year after suffering a hip injury, but is scheduled to return to the stage in September as part of iTunes Festival at Camden Roundhouse in London.
Speaking of which, I'm guessing that rumor that she is going to cover Rolling Stone as their woman of the year in September has gotten a lot more likely given the ARTPOP announcement.
I hope she performs some new songs.
