Mariah Carey Confirms Christmas Duet with Justin Bieber

The biggest “festive collabo” ever is officially happening: Mariah Carey and Justin Bieber are teaming up for a duet on “All I Want for Christmas Is You,” which will be included on his holiday album.

No one loves the winter holidays as much as Mariah does, so it’s no wonder she didn’t wait long since word of this got out to confirm it to fans.

In a video posted on her Twitter page, the diva confirms for her lambs and the Beliebers that, indeed, the two of them will be working together on a version of her hit Christmas song.

It will be included, as we also informed you a while ago, on Justin’s first-ever Christmas album, “Under The Mistletoe,” which will arrive in stores on November 1, just in time to get us into holiday mood.

The LP will also include collaborations with other huge artists, like Boys II Men and Busta Rhymes but, clearly, none is getting the kind of hype that the one with Mariah is getting.
