Watch James Corden with Gwen Stefani, George Clooney and Julia Roberts for Another Carpool Karaoke

James Corden calls on Gwen Stefani to help him get to work, singing her classics along the way until they have to pick up two friends. The trip fetures some of her ’00s hits such as “Hollaback Girl,” “Sweet Escape,” and the No Doubt classic “Don’t Speak.” Halfway through the ride, they hit a four-person HOV lane and so are joined by none other than George Clooney and Julia Roberts.
