Bieber, Usher release Christmas single

Teen singing sensation Justin Bieber has given fans an early Christmas present 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.
