If you were hoping for just a little more One Direction Carpool Karaoke, you're in luck, because the guys give the holiday tune a go (Harry decked in a Santa hat, of course), and even shout out to a couple making out in the streets a hilarious "Get a room!"
Look for James getting his sing on with the 1D guys, Carrie Underwood, Jason Derulo, Iggy Azalea, Rod Stewart, Stevie Wonder, Justin Bieber, and Late Late Show bandleader Reggie Watts.
An instant classic.
