It must be Christmas time because James Corden just gave us two Carpool Karaoke’ segments in one week. He put together an all-star Christmas ‘Carpool Karaoke’ and he got help from the Christmas queen herself, Mariah Carey, as they did “All I Want For Christmas Is You” Check out the video below with a whole bunch of guest stars thrown in the mix.
