An eagle-eyed pedestrian spotted James Corden filming a recent edition of Carpool Karaoke with Justin Bieber and has revealed the car was actually getting a lift on a camera rig. 

However, after the video went viral, executive producer of the Late Late Show with James Corden, Ben Winston, was quick to clarify that Corden does drive, unless it is unsafe for him to do so.

He wrote on Twitter: "We only use a rig when we are doing a 'stunt' as part of the Carpool – when it would be impossible for James to drive!

Fans of the show were quick to make fun of the viral video on Twitter: 

Then the US Late Late Show with James Corden also poked fun at itself with a follow-up tweet:

Corden's version of Carpool Karaoke originated on his US TV chat show, but its popularity has expanded beyond the reach of the show's audience and celebrities have even started asking Corden if they can join him for a singing session in the car.

As a result AppleTV have turned it into its very own programme.
