Late Late Show host James Corden has made his “Carpool Karaoke” bit HUGE, and did a Christmas version this past week!

Although it’s just one song (Joy to the World), a TON of celebrities are in on this one, from Justin Bieber to Stevie Wonder.

Carrie Underwood is also included, showing us once again how flawless her vocals are.  I may be biased…but I think Carrie really steals the show.

Hear her belt it out in the video below!
