Watch: Christmas Carpool Karaoke Is the Gift You Didn’t Know You Wanted

He’s literally been planning this all year. In a special Christmas edition of Carpool Karaoke, James Corden, wearing an offensively bright neon Santa sweater — we blame Pantone’s “Greenery” obsession — straps a colossal pine on the top of his SUV and takes his good friend Mariah Carey out for some last-minute gift shopping. Carey, looking equally festive in a glittery (natch) lace top and red leather jacket confesses that all she wants for Christmas is for Corden to sing a certain holiday anthem. (You know the one.) He — along with basically every guest he’s chauffeured this year — complies. Selena Gomez, Lady Gaga, Adele, Gwen Stefani, Elton John, Nick Jonas and more get in on the Christmas spirit, answering the age-old question, “Does Mariah’s All I Want for Christmas ever get old?”

No. No it does not. As proof, go ahead and try not to sing along to the full clip, above.
