It’s only fair — the biggest New Year’s Eve party in the world should have entertainment by the world’s biggest stars. That means — alphabetically — Justin Bieber and Lady Gaga, both of whom will be performing live in Times Square, along with Pitbull and Hot Chelle Rae, plus Fergie of the Black Eyed Peas from Los Angeles. It’s all part of the 40th Anniversary of Dick Clark’s New Year’s Rockin’ Eve party, hosted by Ryan Seacrest, Jenny McCarthy and the ageless Dick Clark, broadcast on ABC beginning at 8 PM. Street closings begin at 4 PM. Click here for the event schedule from the Times Square Alliance.
