Big Stars Crashed Gwen Stefani’s ‘Carpool Karaoke’ With James Corden [WATCH]

This week’s “Carpool Karaoke” with James Corden featured Gwen Stefani. But two other big stars went for the ride as well. Who were they?

While Gwen sang some of her new songs with James, she also talked about her time as the lead singer of No Doubt. Together, they crooned to the band’s hit single hit single “Dont’ Speak” and  they also tried to act out emojis and goofed in front of the camera. But sometime after in the ride, they decided they would need more people in the car.

Enter George Clooney and Julia Roberts, who gamely joined in singing “We Are The Champions” and Gwen’s other hit, “Hollaback Girl.” Clooney got a kick singing “B-A-N-A-N-A-S!”

Watch as the foursome having fun together in this video below:
