Well, this is a treat.
"The Late Late Show" host James Corden rounded out 2016 by putting together a few familiar faces for his wildly popular segment, "Carpool Karaoke."
It all began with Corden driving around Los Angeles as Mariah Carey and her cleavage sat in the passenger seat. Corden, decked out in a Christmas jumper that would make even Mark Darcy cringe, asked Carey what she wanted for Christmas.
"I want you to sing my song, 'All I Want For Christmas,'" she told Corden, who gladly obliged.
All of a sudden, a clip of Corden and Adele belting out the Christmas classic comes across our screen.
Moments later, it's Demi Lovato and Nick Jonas! Wait, there's Selena Gomez! Oooh, Lady Gaga! Gwen Stefani! Hi, Chris Martin! Seasons Greetings, Red Hot Chili Peppers and Elton John!
Basically it's the a new version of the song absolutely nobody hates, and it's wonderful.
