The celebrity news-consuming public love a good video of their favourite entertainment stars being driven around in cars (Jerry Seinfeld can also attest to that).

James Corden's series on that very topic has amassed more than a billion YouTube views – his video with Justin Bieber pulled in 74 million views alone.

In this latest instalment of Carpool Karaoke, Corden picks up pop singer and former No Doubt member Gwen Stefani for a lift through Los Angeles and a singalong.

They get stuck into her hits, including No Doubt's first big chart success Don't Speak, and Corden gets schooled on the lightning-fast lyrics of her 2006 track The Sweet Escape.

But – oh no – Corden finds that in order to drive in the carpool lane he needs four people. "It's crazy," says Stefani, doing her best acting.

"I know," says Corden, picking up his mobile phone to recruit more car buddies. "This guy, he's got nothing to do."

So who climbs in? None other than George Clooney and Julia Roberts, who are currently promoting their new film Money Monster.

No doubt the main draw of this video will be the sight of these two Hollywood heavyweights singing along to Stefani's Hollaback Girl – and then proceeding to deconstruct what the song is about.

The group then move on to We are the Champions by Queen before going their separate ways.

James Corden certainly has the power to pull in the biggest of stars – can he top this one?
