Mariah Carey is helping Justin Bieber spread the holiday cheer this season…

The 41-year-old part-Venezuelan songstress and the Biebs revealed the video for their re-do duet of Carey’s own insta-holiday-classic “All I Want for Christmas” during NBC’s Christmas in Rockefeller Center special on Wednesday night.

The clip, was filmed after hours at the Macy’s Department Store, features Santa Claus spreading tidings of comfort and joy on the street, before moving indoors where Bieber and friends encounter Carey belting out the iconic Christmas tune in a barely-there Santa suit.

Carey and Bieber trade verses in the high-energy video before appearing in a sleigh together and handing out gifts to shoppers.

“All I Want for Christmas” is the second single off of Bieber’s holiday album, Under the Mistletoe. The album features a mix of traditional holiday standards and original tracks.
