Mariah Carey is teaming up with John Legend for a remix of one of her earlier Christmas songs. The duo will collaborate on a remix of Carey's "When Christmas Comes," which was released as part of Carey's 2010 holiday album Merry Christmas II You and originally produced by The Roots' James Poyser. A sneak preview of the forthcoming video has already been released, with Carey riding a car through a snowy landscape and lip-syncing to her own song as it blasts from the car's radio, sung by Legend.

Carey told her fans of the upcoming collaboration by posting a snippet of the video on Twitter: "Coming soon, a legendary musical collabo. #WhenChristmasComes Sorry for the camera work, the snow made it pip! So . . that was a snippet of the RnB Christmas collabo - me & the legendary John, soon to be topping your Christmas list! P.S. It's a SGSHW!"Carey will also be releasing a collaboration with Justin Bieber on the traditional Christmas tune "All I Want For Christmas Is You," with the video now in production.
