On the December 4, 2012, episode of Late Night with Jimmy Fallon, Mariah joined Jimmy Fallon and The Roots to sing a special rendition of her self-penned Christmas classic “All I Want For Christmas Is You” using classroom instruments.
Mariah visited Late Night with Jimmy Fallon in March 2003 to talk music, her judging gig on American Idol, and to play a game of Champagne Pong.
Mariah surprised a roomful of her lamb on the release day of her new single “The Art Of Letting Go” on Late Night with Jimmy Fallon. The host invited some of them to a recording studio under the guise of hearing Mariah's new song for the first time — but Mariah was actually singing the song live in an adjacent soundproof booth walking out to surprise the group!
Mariah visited Late Night with Seth Meyers in December 2016 for the host's first-ever sleigh interview. They discussed “All I Want For Christmas Is You” and Mariah's Christmas traditions.
