Carpool Karaoke is one of our favourite things in the world.

There’s just something about seeing super famous celebs belting out their own tunes on a dash cam!

And the latest guest, Gwen Stefani, would have been amazing all by herself but James Corden ended up pulling over and picking up two more stars on the way in the latest instalment of the popular segment.

And they  were none other than George Clooney and Julia Roberts.

Enjoy this one, it’s AMAZING.
