James Corden, host of "The Late, Late Show," has managed to turn his Carpool Karaoke segments into one of the most watched series on YouTube. He had to have an extra special singing-while-driving duet for the holidays, and he did so by inviting the first celebrity to ever guest on the series, Mariah Carey, back into his passenger's seat. With a car full of presents, the clip begins with Corden and Carey -- whose cleavage game, at age 46, is still second to none -- discussing Christmas shopping, before breaking into song. The obvious choice was Carey's own "All I Want for Christmas Is You," one of the all-time classics of the holiday genre.
Before long, the scene cuts to clips of past Carpool Karaoke alums -- Chris Martin, Gwen Stefani, Selena Gomez, Demi Lovato, Nick Jonas, the Red Hot Chili Peppers, and Elton John -- singing along to the same song. If this doesn't get you in the holiday spirit, then I don't know what will. Maybe The Return of East Atlanta Santa is more up your alley.
