Lady Gaga kicks off Roseland residency...

Lady Gaga's week-long residency at New York’s Roseland Ballroom kicked off right as she celebrated her 28th birthday. Only 28, can you believe? I know I can't. During the show, Gaga performed old hits and new songs off her current album 'ARTPOP', including latest single 'G.U.Y.', live for the first time. 

Good news is, no vomit was involved. Check out the dance heavy performance inside.
