Mariah Carey [1] brought a little Christmas magic to the stage when she performed her hit "All I Want For Christmas Is You" during the taping of VH1's Divas Holiday: Unsilent Night in Brooklyn on Friday. In true Mariah form, the singer made a grand entrance in a red sleigh wearing a sultry nutcracker costume. Aside from showing off her killer pipes, she also flaunted her new beau [2], Bryan Tanaka, as he danced alongside her for the number. Catch a sneak peek of the performance above before the special airs on Dec. 5.
