James Corden's Carpool Karaoke has given us some excellent moments throughout the year, from Adele rapping Nicki Minaj's legendary 'Monster' verse to Madonna throwing some in-seat gymnastics.
However, little did we know that some of the stars that have graced the world's most famous passenger seat have been contributing to a Carpool Karaoke festive bonanza. And the finished product is an all-star rendition of the best Christmas song of all time. (Yes, we said it).
In the video, Adele, Elton John, Lady Gaga, Red Hot Chilli Peppers, Selena Gomez, Demi Lovato, and Nick Jonas each take turns singing the notoriously difficult-to-sing Mariah Carey classic, 'All I Want For Christmas Is You'. Of course, no one can do it quite like the diva herself.
Luckily, Ms. Carey is on hand to show everybody else exactly how it's done.
