Carpool Karaoke is already one of the funniest and best things we could ever watch, but it just got a whole lot better! How does James Corden manage to keep topping himself?! Not only did he get Gwen Stefani to be his passenger, singing along to hit songs, but they managed to pick up George Clooney and Julia Roberts! Only two of the most legendary actors of our time!

The video is just too good to be true. Ain’t no hollaback girl!
