James Corden put together a special all-star Christmas “Carpool Karaoke” with help from Mariah Carey.

Not only do they sing her classic Christmas hit, “All I Want for Christmas Is You,” but they get a little extra help from some of your favorite A-list stars. Lady Gaga, Selena Gomez, Adele, Demi Lovato, Nick Jonas, Chris Martin, Elton John, Gwen Stefani, and more all get festive in the holiday clip.

Basically, every single musician that Corden had on “Carpool Karaoke” as a guest this year made the cut — minus a few, such as Madonna and Bruno Mars.

Clearly, the video has been months in the making, and we couldn’t be more grateful for this holiday treat! Watch the star-studded Christmas Carpool Karaoke above!
