George Clooney and Julia Roberts Join Gwen Stefani's Carpool Karaoke

If you’ve ever wanted to see George Clooney sing along to Gwen Stefani’s “Hollaback Girl,” now’s your chance. Filmdom’s Pretty Woman joining in as well is just icing on the cake.

Clooney and his Money Monster co-star Julia Roberts joined the Voice coach and James Corden for the latest installment of The Late Late Show‘s Carpool Karaoke Wednesday, jamming out to Stefani’s songbook as well as Queen’s beloved “We Are the Champions.”

The three-time Grammy winner also managed to drop a few lines from recent chart-topper “Used to Love You” and the unforgettable No Doubt track “Don’t Speak” prior to the arrival of Oscar royalty.
