Adele and James Corden duet in 'best ever' Carpool Karaoke

Adele has become the latest star to join James Corden for an epic car singalong - and some are calling it the "Best Carpool Karaoke ever".

The two belted out some of Adele's biggest hits, including Hello and Someone Like You, as well as a surprise Spice Girls cover as they drove around London.

The global star also rapped to Nicki Minaj's Monster to the delight of the Late Late Show host.

The guest passenger is revealed when Corden is heard on the phone saying: "Hello, it's me. I was wondering if after all these years you'd like to meet?

"Hello from the outside."

The pair also discussed hair during the hilarious skit.

"I was going to wear a wig. I can't work out if I should wear a wig, or wear a weave," she said.

Corden replied: "What I love is that you're coming to me for this advice."

The segment from Corden's popular US talk show has also seen the Gavin and Stacey actor singalong with pop royalty Stevie Wonder and Justin Bieber.
