Lady Gaga performed her new single 'G.U.Y' on The Late Show with David Letterman on April 2. Check out footage below.
The star is currently in the midst of a residency at New York's Roseland Ballroom, and reportedly popped over the road to the Ed Sullivan Theatre to invite the Letterman audience over to her venue for an impromptu performance.
According to CBS New York, Gaga, Letterman, the audience and Bill Murray (OBVIOUSLY) then walked over to the Roseland, which must have been a rather surreal sight.
Gaga then performed her latest single from ARTPOP, 'G.U.Y', clad in a towering green wig.

Gaga is currently in the middle of a 7 date residency at the iconic Roseland Ballroom, which is set to close for good after the 'Applause' singer's final show on Monday April 7.
