Justin Bieber Pumps Up The Party

Justin Bieber brings the crowd to their feet as he performs a surprise mini-concert during the 2010 Nickelodeon Upfront Presentation at Hammerstein Ballroom in NYC on Thursday morning (March 11).

The 16-year-old musician hung out with Nick ladies Miranda Cosgrove and Victoria Justice as well as the Big Time Rush guys.

According to Rap-Up.com, Justin‘s new album, My World 2.0, comes with another golden ticket — an all-expenses paid weekend at the Atlantis Paradise Island resort!

Four lucky fans will get the chance to meet Justin in the Bahamas and will also get to meet their idol in-person and attend his concert on June 12. Can JJJ go?
