All we want for Christmas is to watch this Carpool Karaoke over and over. James Corden called up pal Mariah Carey for a holiday version of his famous late-night skit. Fun, of course. But the video then cut to all of the celebs who have done Carpool Karaoke this year – Selena Gomez, Adele, Chris Martin, Demi Lovato et al – belting out Carey’s “All I Want for Christmas” in one glorious mash-up. 

The only thing that could have made this better is if Mariah wore an ugly Christmas sweater.
