Everybody loves this song. And everybody loves James Corben. Add numerous celebrities, and you have yourself the best carpool karaoke ever!
Watch Lady Gaga, Demi Lovato, that dude from Coldplay, Elton John and more perform this beloved Christmas classic, together with the fantastic James Corben.
I think my favorite must be the RHCP – and yours? Share it with your friends and I dare you not to sing along!
