Justin Bieber isn't keeping any of his new 'Under the Mistletoe' album a secret. The 17-year-old worldwide superstar has been hard at work in the studio getting ready for the big release day (Nov. 1), and he wants all of his fans to share in the experience through weekly webisodes. This week, the Biebs is leaking his studio sesh with Usher on 'The Christmas Song.'

Like the rest of the holiday album, this Christmas-inspired track will be a modern take on more traditional classics. The "chestnuts roasting on an open fire" tune brings out Biebers beautiful vocals, which remind us of an angel and warm us up from the inside out. Additionally, it's Usher-infused -- and given that he's the Biebs' mentor, we know it won't be a sleepy moment on the new Xmas album.

Biebs' first holiday singler, 'Mistletoe,' hit just last week, and the Bieber/Usher collab will hit your ears as soon as Monday, Oct. 24, so click back to PopCrush to hear it in full. 'Under the Mistletoe' -- the album -- is out November 1.
