Fans at U2's Madison Square Garden concert Sunday got an extra surprise when pop-superstar Lady Gaga hopped onstage for an impromptu duet with the Irish rock giants.
Bono happily invited the singer up, jokingly calling her "Her Gaganess" as she made her way to the piano. The pair then jumped into a performance of "Ordinary Love," the Oscar-nominated song written for the Nelson Mandela biopic Long Walk to Freedom.

In true Gaga fashion, the singer donned a bra, panties, pantyhose and a killer pair of Alexander McQueen Armadillo boots. No stranger to stadium shows herself, she commanded the stage from behind the piano.
U2 is currently in the middle of an eight-show run at MSG, which could mean more surprise guests are on the way.
