This A-List "Carpool Karaoke" Just Won the Internet For the Holidays

It's a very merry, Mariah Christmas in these streets.

Just when you thought James Corden couldn't top his "Carpool Karaoke" with a loose-lipped Madonna's confession on Michael Jackson, he did this.

Mariah Carey is the latest to join James Corden on a joy ride in the most recent episode of "Carpool Karaoke."

As a homage to the holidays, the host got the queen of Christmas carols to jam out to her 1994 classic, "All I Want for Christmas," but it didn't end there. Early into Mariah belting out the hit melody, a slew of famous faces singing along to her song, for an epic mash up of A-list guests singing the same track. The montage includes everyone from Adele, Elton John, Lady Gaga, Gwen Stefani, Chris Martin, Demi Lovato and more.

The brilliant project was months in the making, as it is clear that guests shot the footage during past episodes of the show.

It's still early, but something tell us that James Corden just won Christmas (and possibly saved 2016). Everyone can relax now.
