Seven years have passed since Mariah Carey released her hit Christmas song "All I Want For Christmas Is You," and now Justin Bieber has joined Mimi for a new re-make. Check out these photos of the twosome on set of the new video. Thanks for sharing the pics, Mariah!

Ms. Carey looks oh-so-cozy on Santa's sleigh. Perhaps the mama of two will be giving Biebs a ride!

The new track is featured on the 17-year-old singing sensation's Xmas album, Under the Mistletoe.
