Lady Gaga hits the stage in the middle of Times Square to perform a medley of her hits on New Year’s Eve (December 31) in New York City.

Gaga began her performance wearing a sequined octopus suit and then stripped out of it to reveal a ball surrounding her head.

A few minutes after she performed on Dick Clark’s Rockin’ New Year’s Eve telecast, Gaga joined Mayor Michael Bloomberg to launch the ball drop to mark the new year.
