Justin Bieber's Christmas album seems like it's set to be the next big thing!

Bieber and mentor Usher debuted their recording of classic Christmas tune "Chestnuts Roasting On An Open Fire" on Monday, and, of course, Beliebers went crazy!

Justin re-Tweeted one fan's Tweet, which read, "i am cryin happy tears lol i am at school but #chestnuts is just so beautiful <3"

God bless us, everyone!
