​Watch Mariah Carey, Adele, Elton John, Red Hot Chili Peppers on Christmas Edition of 'Carpool Karaoke'

The Late Late Show host James Corden has offered up another instalment of his hit Carpool Karaoke segment — and this one's a huge holiday supercut of stars singing one of the greatest Christmas songs of all time.
 
Mariah Carey sits shotgun first, asking Corden to sing her classic, "All I Want for Christmas Is You." To everyone's delight, a barrage of stars that have previously appeared on the show jump in with their own pre-recorded renditions of the song.
 
Adele, Demi Lovato, Nick Jonas, Elton John, Selena Gomez, Lady Gaga, Gwen Stefani, Coldplay's Chris Martin and Red Hot Chili Peppers all make their own festive contributions to the track, and you can see it all happen in the player below.
