Teen singing sensation Justin Bieber gave fans an early Christmas present on Monday with the release of a second single from his upcoming holiday album Under The Mistletoe.

The single, Chestnuts Roasting On An Open Fire, is a festive R&B ballad on which Bieber duets with his mentor, Usher. The 17-year-old singer previously collaborated with Usher on the single Somebody to Love from his multi-platinum debut album My World 2.0.

The new song premiered on celebrity Ryan Seacrest's radio show On Air With Ryan Seacrest, and comes a week before Bieber's highly anticipated Christmas album is released, featuring collaborations with Usher, Mariah Carey, Boys II Men, The Band Perry and Busta Rhymes.
