Watch Mariah Carey, Adele, Elton John and More on James Corden’s Christmas Carpool Karaoke

All we want for Christmas is to be allowed to sit in the backseat!

We must have been very good boys and girls this year, because Santa has given us quite the early Christmas gift! 

Following earlier this week's amazing carpool karaoke performance from Bruno Mars, the hilarious James Cordon is back with a star-studded Christmas edition. 

In the fabulously festive clip above, The Late Late Night Show host starts by driving around LA per his usual routine but this time there's a Christmas tree on the top of his car and lots of presents in the back. Superstar and Christmas crooner Mariah Carey then reveals herself and tells James that the only thing that she wants this Christmas, is for him to sing her smash holiday hit. 

As if Mimi and James singing 'All I Want For Christmas' isn't magical enough, it turns out that James has been planning this surprise all year long and taped a sampling of his previous celebrity passengers singing along! 

That's when the video cuts to clips of guests belting out their best Mariah Carey, including Adele, Chris Martin, Elton John, Demi Lovato, Nick Jonas, Selena Gomez, Gwen Stefani, Lady Gaga, and even the Red Hot Chili Peppers!

The result? The most amazing holiday sing-along we could have asked for. Thank you James!
