Justin Bieber has teamed up with his mentor Usher to record a new version of festive classic The Christmas Song (Chestnuts Roasting On An Open Fire).
The stars' cosy duet will feature on Bieber's upcoming holiday album Under The Mistletoe, and Usher thinks the pair has recorded a classic that will become a festive favourite for years to come.
He says, "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."
Bieber has also teamed up with Mariah Carey on the album.
