There is no denying that Mariah Carey's 'All I Want for Christmas Is You' is a new holiday standard. Nicki Minaj's nemesis even redid the song with Justin Bieber, proving its got legs longer than Mimi's! She performed the song, in a sexy little Santa outfit, in Rockefeller Center in New York City last night (Nov. 27.) The performance was taped for a special that airs tonight. Can't wait? Then watch it here.

Carey looks like Mrs. Claus with her red gloves, too, doesn't she?

She didn't stir up merriment, mirth and cheer with one song, though. She also performed the slower 'Christmas Time Is in the Air Again' from 'Merry Christmas II You.' A diva of Carey's stature can't wear the same outfit for two songs in her performance, so she swapped our her cutesy outfit for a white ensemble.

With a fur shrug and a long, column gown with a flower in her honey-hued hair, she was a vision in white and looked much more glamorous for the ballad. The Santa outfit was appropriate for her upbeat anthem and this dress was just right for a slower, torchier number.

She was flanked by bright, white Christmas trees. What an accessory, Meems!
