We must have been very good this year because Santa just delivered us one heck of an early Christmas present. And by Santa, of course, we mean the holly jolly James Corden.
On tonight's new episode of The Late, Late Show, James delivered some much needed holiday cheer in the form of a new Carpool Karaoke—the second of the week after Tuesday's drive with Bruno Mars! Riding shotgun this time around? The queen of the modern day Christmas song, Mariah Carey.
Only, this was no regular Carpool Karaoke. What seemed like an innocent duet between the pair to Mimi's classic "All I Want for Christmas Is You" turned into a surprisingly star-studded sing-along, mashing up familiar faces from CK segments of yore, all singing along to the same epic track.
Adele, Demi Lovato, Nick Jonas, Selena Gomez, Chris Martin, Gwen Stefani, Elton John, Lady Gaga, and even the Red Hot Chili Peppers all joined in on the song, thanks to unseen footage from other Carpool Karaoke segments this year.
It was basically the most epic sing-along we could have asked for, even if "All I Want for Christmas Is You" is now even more embedded in our heads than it was before. Luckily, that's not something we'd ever complain about.
The Late, Late Show airs weeknights at 12:37 a.m. on CBS, and Mariah Carey can be seen in her docuseries Mariah's World, airing Sundays at 9 p.m. on E!
