"Carpool karaoke" is a favorite on The Late Late Late Show with James Corden.
On May 4, the segment included superstar Gwen Stefani. Gwen and James sang some of No Doubt's biggest hits including "Don't Speak."
Halfway through the bit, Gwen and James were joined by Hollywood A-list movie stars George Clooney and Julia Roberts.
The foursome's rendition of Queen's "We are the champions" will make you sing along at the top of your lungs!
