WATCH: Stevie Wonder gets behind the wheel with James Corden

We take it all back - THIS has to be James Corden's best sketch yet.

Carpool Karaoke with no other than Stevie Wonder himself.

After a rough start, in which we learn that Wonder “forgot his license” and was unable to drive the host to his destination, it kicks off with him busting out some tunes on his famous harmonica.

In between renditions of 'Isn’t She Lovely', 'Signed, Sealed', Delivered and multiple Facetime calls, Wonder decides he likes Corden so much that he wants to form a group with him called The Wondercats.

“We’re going to write new lyrics to Stevie Wonder songs,” he proclaimed before the duo finished up the ride with 'For Once in My Life'.

WARNING: It all gets a little emotional at one point when the music legend rings Corden’s wife Jules: "I just called to say James loves you".

This might just be one of our favourite celeb bromances to date.
