As if a Carpool Karaoke with Gwen Stefani wasn’t awesome enough, James Corden nabbed two A-list actors to join in on their jam session.
On Wednesday, May 4, the singer joined The Late Late Show host for a carpool ride and rocked out to some of her biggest hits including “Don’t Speak” and “Hollaback Girl.”
Things got even more exciting when George Clooney and Julia Roberts jumped in the car and sang right along with them.
Watch the hilarious video below to see the Academy Award winners show off their vocals.
