Nothing like some Christmas music to get your into the holiday spirit. James Corden had everyone join in on singing "Santa Claus Is Comin' To Town" and it's Carpool Karaoke perfection.
Get ready to spot all your faves - Pink, Bruno Mars, Miley Cyrus, Sam Smith...the list goes on and on. And you'll even witness a lil smooch between James and Harry Styles, WHAT! Check it out and get ready to sing along!
