Just when you felt like the week was dragging along, James Corden delivered another Carpool Karaoke to remember on the Late Late Show

This time, Gwen Stefani was in the passenger seat, discussing her favorite emojis and singing duet versions of her best hits including throwbacks like “Don’t Speak,” “The Sweet Escape” and “Rich Girl.” But things got really good when pals George Clooney and Julia Roberts spontaneously hopped in the back. 

Watch the clip and cry-laugh as the four dissect Gwen’s lyrics and attempt to harmonize together.
