James Corden shimmied on down the YouTube chimney to deliver us a very merry Christmas carpool karaoke. On Thursday, The Late Late Show host dropped his annual festive song mashup with the celebrities who joined him in the front seat this year. Evidently, when James and Cardi B weren't performing at a senior centre, they were recording a snippet for this music video. And after Ariana Grande injured her hand during her appearance, she still had enough Christmas cheer to belt out a few beautiful notes. Other stars who are featured in the seasonal serenade include Shawn Mendes, Paul McCartney, Barbra Streisand, and Michael Bublé. Watch them add their own twist to the upbeat karaoke rendition of "Christmas (Baby Please Come Home)" in the clip above. And in the words of Quavo from Migos, "Merry Dripmas!"
