Justin Bieber & Mariah Carey to Duet on 'Under The Mistletoe'

We already know that Boyz II Men and Usher will collaborate with Justin on his upcoming Christmas album, Under The Mistletoe. Now we have word of another duet, this one with none other than Mariah Carey! One of Justin's dancers tweeted this: ":) RT @justinbieber @mariahcarey HONORED." As JustinBieberZone said, he followed up with this: "had to tweet that cause apparently people didnt believe me. haha justin bieber featuring mariah carey. believe it."

Boyz II Men will be great because Justin has looked up to them all his life. And Usher is a special one since he is Justin's mentor. But Mariah Carey is a big get for the album, since she's one of the best singers in the world, with one of the greatest vocal ranges ever.

Under The Mistletoe will be released on November 1, and is now available to pre-order online in both standard and CD/DVD Deluxe versions. To pre-order a copy, below are the Amazon product links (or pre-order them directly from the Bieber Guy STORE).
