One of my favorite things about 2016 has been Carpool Karaoke. And though I can have Grinch-like tendencies, nothing gets me in the holiday spirit more than All I Want for Christmas is You. Thankfully, James Corden picked up Mariah Carey in his car to sing along to the greatest Christmas song of all time.
Corden, appropriately dressed for National Ugly Sweater Day, is not just joined by the Diva herself; there's a cadre of past Carpool Karaoke-ers who belt it out to the chart-topping tune, including Lady Gaga, Elton John, and Adele.
Grab some hot cocoa, turn on the tree, and enjoy:
