Here's One Direction & Justin Bieber Doing Carpool Karaoke, Christmas Style

Because James Corden is quite clearly Santa, he's gifted us with the most wonderful present of all: Harry Styles wearing a Santa hat singing Joy To The World.

Thanks carpool karaoke, we are forever in your debt.

A super cut of all of his best ones yet, James sings the Christmas classic with the likes of One Direction, Justin Bieber, Stevie Wonder and more, high notes included.

It really is the most wonderful time of the year!
