Gwen Stefani's Carpool Karaoke Was Crashed By George Clooney And Julia Roberts

As if Gwen Stefani doing James Corden's Carpool Karaoke wasn't exciting enough already, two of the biggest Hollywood actors decided to join them for the ride this week.

Yep, actual real life George Clooney and Julia Roberts hopped in to help the Late Late Show host get to work, never ones to pass up a chance to hang out together.

While not only do they sing Hollaback Girl, but they also all get involved with quite the stirring rendition of We Are The Champions. No really, they ~go for it~.

Right that's it, this weekend will now be dedicated to re-watching Notting Hill. And Ocean's Eleven. And Ocean's Twelve.

This also makes us incredibly excited for Nick Jonas and Demi Lovato's turn later this year...
