Under unseasonably warm weather, hundred of thousands of people gathered in New York to watch celebrities and the city's mayor do the countdown.
Lady GaGa rang in the new year with her fans at Times Square, performing before them as part of Dick Clark's New Year's Rockin' Eve telecast. During her set, she sang a medley of "Heavy Metal Lover", "Marry the Night" and "Born This Way" while wearing extravagant outfits.
Hundred of thousands people gathered at the place to watch a crystal ball descended at midnight. GaGa and NY mayor Michael Bloomberg led the countdown and pushed the button. As the ball came down, GaGa smooched Bloomberg and danced to "Auld Lang Syne". Frank Sinatra's "New York, New York" was then played.
Beside GaGa, Justin Bieber and Pitbull were among the performers who entertained the crowd as they waited for 2011 to fold. Bieber in particular made a surprise duet with Carlos Santana on The Beatles' "Let It Be". Ryan Seacrest was back to host the televised event.
