Teen heartthrob Justin Bieber has decided to give his fans an early Christmas treat in the form of his new song with Usher.

The Christmas Song is the second single released from his forthcoming holiday album Under the Mistletoe. Prior to this, Bieber collaborated with Usher on another single Somebody to Love from the album My World 2.0.

The new single was released Monday on Ryan Seacrest's radio show.

Justin and I did the classic record 'Chestnuts Roasting on an Open Fire.' This record is going to be remembered for years to come, MTV quoted Usher as telling Seacrest on Monday morning.

It's a record that has always been one of my favourites, and I'm happy that I was able to share it with Justin, and for us to put it out. The album is full of surprises. Justin's Under the Mistletoe is going to be incredible, Usher added.

Apart from Usher, Bieber has also collaborated with Mariah Carey, Boys II Men, The Band Perry and Busta Rhymes for his next album.
