Christmas came early this year in the form of not one but two Carpool Karaoke segments this week. Last night, James Corden was joined by the OG Carpool Karaoke guest Mariah Carey and sang along to her classic hit "All I Want for Christmas is You." The pair teamed up with a special cast of all-star celebrities including Adele, Lady Gaga and Selena Gomez.
The video brought things full circle by featuring celebs that appeared in past Carpool Karaoke episodes. Ending the year with a special holiday-themed segment was the perfect way to round out 2016. And it was a throwback that we didn't know we needed because this song is the ultimate karaoke song and has been getting us into the holiday spirit for decades.
