Justin Bieber, Mariah Carey flirt for Christmas (+video)

Deck the halls, Beliebers!

The video for Justin Bieber and Mariah Carey's new version of her classic holiday staple All I Want for Christmas Is You has debuted.

The teen titan unveiled the Sanaa Hamri-directed clip during the Rockefeller Centre Christmas tree lighting ceremony in New York City on Thursday.

The promo sees the Canadian crooner, 17, go wild in the tinsel-themed aisles of a department store (Macy's, no less) with a gaggle of his gift-hunting pals.

Meanwhile, a scantily clad Carey, 41, wriggles and writhes in her skimpy Santa-inspired clobber.

There's also a sleigh, a puppy and ... hang on, are they flirting?!

"WATCH "All I Want For Christmas Is You" #SuperFestive version with @justinbieber NOW!" tweeted Carey ahead of the video's premiere.

The souped-up version of Carey's 1994 megahit features on Bieber's new Christmas album, Under the Mistletoe.

So what do you think? Festive cracker, or jingle hell?
