It’s officially Christmastime, so get ready to overdose on Mariah Carey’s All I Want For Christmas Is You. Pop's patron saint of the holidays kicked off the season by performing with Jimmy Fallon and The Roots in a viral video that made its round even faster than Santa on Christmas Eve.

Decked out in Christmas colors, Mariah hit those high notes while children in festive sweaters sang along with her and the band. If this doesn’t have "holiday spirit" written all over it, we don't know what does.

This isn’t the first time Jimmy has rocked out with a pop star. Last summer, he brought in Carly Rae Jepsen to do a special performance of Call Me Maybe that, yes, went viral. Is it safe to assume that we'll be hearing Mariah’s poppy Christmas carol every day until December 25 from here on out?
