It's a very merry Carpool Karaoke!

Wearing a fire-engine red leather jacket, Mariah Carey joined James Corden to get in the festive spirit, singing "All I Want For Christmas" during their fun-filled ride on the The Late Late Show on Thursday,

But it wasn't just Mimi singing her hit tune, Adele, Lady Gaga, Nick Jonas, Sir Elton John, Selena Gomez and others joined James in the passenger seat -- and it was pretty epic!

The segment kicked off with the diva sitting in front of a plethora of gift-wrapped presents sitting in a car full of festively wrapped gifts with Corden as he thanks her for helping him with his holiday shopping. "What would you want for Christmas?" he asks the Grammy winner.

She responded, "I don't know. I don't want to ask for something too expensive or too nice. I want you to sing my song," she says.

Umm we love this so hard!
