The 38-year-old TV host would love to work with the 'Allied' actor on a project or maybe have him appear on 'The Late Late Show'.

He said: "I would love to film something Brad Pitt. Not a 'Carpool Karaoke', just something fun. I just dig him. I think he's really funny."

Meanwhile, James has confirmed that pop superstar Bruno Mars is to appear on 'Carpool Karaoke'.

He told ET Canada: "It's the most fun I've had in the car.

"I can't wait to see it. I've never had that much fun doing work ever in my life."

The British comedian has also praised Mariah Carey's for her dedication to her forthcoming episode.

He said: "None of it would exist without her.

"We owe her a huge amount of gratitude.

"Her vision to be able to see what it could be, and say yes to doing it is the very thing which has made our show what it has become."

And earlier this week, Madonna confirmed that she will also appear on 'Carpool Karaoke' as she shared a picture of herself and James on Instagram.

She captioned the image: "Riding around Manhattan with this Hunk of Burning Love @latelateshow carpool karaoke (sic)"

'The Late Late Show' Instagram account also shared the same picture, with the caption simply containing three praying emojis in reference to Madonna's hit singe 'Like a Prayer'.

'Carpool Karaoke' features Corden, 38, picking up a star in his car, and interviewing them whilst the pair sing along to some of their biggest hits. Previous guests on the segment have included Lady Gaga, Selena Gomez, One Direction, and Adele.
