In addition to debuting his new single 'Mistletoe,' Justin Bieber was full of good news this morning! The Biebs and Ryan Seacrest confirmed on the latter's radio show that The Biebs will perform on 'Dick Clark's New Year's Rockin' Eve.'

The Biebs will join the already announced Lady Gaga and Pitbull for the festivities and help ring in 2012! You know what that means? It means that you can grab some drinks and snacks, invite a batch of friends over and watch the ball drop on 2012 in the comfort of your living room. Since the entertainment will be so quality, you don't need to go out. You can bring the party to your living room.

The big reveal was sort of off the cuff, too! Seacrest said that he knew where The Biebs would be on New Year's Eve and the singer then chimed in, "I think I'm going to be with you," to which the 'Crest responded, "Yeah, in Times Square!" Once the leak was out, it was out, and Seacrest even joked, "Justin's the boss" and that's why they were allowed to reveal it now!

The Biebs also shared details of his familial Christmas customs, saying that he spends Christmas Eve with his mom's family and spends Christmas Day with his dad! Double the fun, right?

But before we go speeding headfirst into Christmas, there's another holiday on the horizon that we're curious about. The Biebs joked that he would be going as Ryan Seacrest for Halloween. Could you picture it?
