Just when I thought I had seen the best of Carpool Karaoke with The Late Late Show with Host James Corden, he pulls together this amazing montage of past guests.

James who is no slouch in the singing department, pulled off the most epic montage of "Joy to the World" with a ton of guests, including One Direction, Stevie Wonder, Justin Bieber and more. On top of all of this, I love how when James was on Ellen recently, that she had told him she was so jealous of how he thought of this idea first.

Well look Ellen, I think you are awesome and super funny, but James is actually a really good singer, and that is how he is able to pull it off. She is going to have to stick to her dance routines and scaring people.
