Last year, James Corden produced an epic Holiday Carpool Karoke with celebs singing Mariah Carey's "All I Want For Christmas is You." He did a great job pulling together celebs from all over for "It's Christmas (Baby Please Come Home." Christina Aguilera, Ariana Grande, Shawn Mendes, Paul McCartney, Cardi B, MIchael Buble, Migos and Adam Levine were all a part of this. Enjoy! Happy Holidays!!!
