The Carpool Karaoke idea was a bit of genius.
We all have our favourite guests, but who actually won out in terms of social media buzz?
Well, Twitter have done some serious number-crunching to figure out who the most buzzed about carpool guests are.
Adele might have been the most-viewed one on YouTube, but did she win out in terms of people tweeting about her appearance in James Corden's car?
Apparently, no.
The winners by a long shot were beautiful boyband One Direction, who sit comfortably in the top spot, followed by Justin Bieber in second and third place.
