Our Christmas wishes have finally been answered! Mariah Carey hopped in the car with James Corden for a special holiday version of Carpool Karaoke and there are some VERY special guests.

This might be the BEST Carpool Karaoke YET! I know, I know…I say that every time, but this time I’m serious! Mariah, Adele, Elton John, Lady Gaga and MORE surprise us with a very special gift for Christmas.

I guarantee you’ve NEVER heard “All I Want For Christmas Is You” quite like this before. This. Is. Everything.
