Watch Mariah Carey Headline A Star-Studded Christmas Carpool Karaoke

Some Christmas songs are such bangers that one pop star is not enough.

Even if Mariah Carey never wrote or sang another note, she would have made an indelible contribution to our culture by singing and writing "All I Want For Christmas Is You." The proof is that the song has gotten to be bigger than Carey herself, as we see in The Late Late Show's Carpool Karaoke, in which just about everyone who Carpool Karaoked with host James Corden this year is montaged together. If you need an injection of festive spirit, this will do it!
