All I Want for Christmas Is You: Mariah Carey and more stars sing with James Corden in special edition of ‘Carpool Karaoke’

James Corden prepared a very special holiday surprise this year: another epic Christmas-themed "Carpool Karaoke" mashup.

Driving around with Mariah Carey, Corden asked the superstar diva what gift she wants the most this year, and all she wanted for Christmas was for Corden to sing her holiday hit, “All I Want For Christmas Is You.”

And then the clip cuts with Gwen Stefani, Lady Gaga, Elton John, Selena Gomez, Demi Lovato and Nick Jonas, Chris Martin Adele and even The Red Hot Chili Peppers joining the song.
