One Direction, Justin Bieber And More Bring ‘Joy To The World’ With Christmas Carpool Karaoke

This is the only holiday song you need.

James Corden is the gift that keeps on giving.

The "Late Late Show" host has been treating us with his Carpool Karaoke series over the course of the year, and throughout that time he's been working on something pretty special, a Christmas-themed karaoke ride.

Justin Bieber, Iggy Azalea, Jason Derulo, Carrie Underwood, Stevie Wonder, Rod Stewart and One Direction (with Harry Styles in a Santa hat) all make appearances as they belt out a truly joyous rendition of "Joy To The World."

Justin and 1D hit some pretty impressive high notes, Carrie is all about the vocal runs and Iggy injects a little bit of an Xmas rap to make this three minute clip a true holiday celebration.
