Video: Lady Gaga turns 28 and treats fans to a brief gig
Lady Gaga has celebrated her 28th birthday with an energetic but short concert in New York.
Gaga, who performed for an hour in front of a feverish crowd at the Roseland Ballroom, was on top form as she sang nearly a dozen of her songs, including Just Dance, 'Born This Way, 'Poker Face and Applause.
The shortness of the concert surprised fans, who waited for the pop star to hit the stage again after she had actually finished.
The New York-born singer performed some tracks from her recent album, ARTPOP, which has struggled to match the success of her other releases.
But on stage, she showed no signs of slowing down.
Gaga's actor-boyfriend Taylor Kinney attended the concert at the closing venue.
