Lady Gaga did a whole lot when she kicked off her Roseland Ballroom residency in New York on Friday night (Mar. 28), but one thing the pop provocateur did not do was expose her backside. That changed on Sunday night during her second performance, when she pulled down her purple bottoms and mooned the packed crowd.

The incident occurred in between songs, when Gaga turned around and nonchalantly flashed her derriere while strolling toward the back of the stage. Of course, Gaga's flashing comes nearly eight months after the "ARTPOP" star appeared completely nude in a video for the "Ambramovic Method," if that helps lower your eyebrows a bit.
