Justin Bieber to join Lady Gaga for 'New Year's Rockin' Eve'

The annual craziness that is New Year's Eve in Times Square just got a lot wilder as Justin Bieber is confirmed to perform on ABC's "New Year's Rockin' Eve."

Bieber joins Lady Gaga on the card for the mid-town concert. This also means that Beliebers will be standing shoulder to shoulder with Gaga's fans, the Little Monsters. So that should be interesting.

The program features five and a half hours of performances from New York and around the world. While Ryan Seacrest will anchor the East Coast countdown, the West Coast portion will be hosted by Fergie from The Black Eyed Peas.

ABC begins the broadcast at 8:00 p.m. ET on Dec. 31.
