James Corden says it's impossible to do 'Carpool Karaoke' without being in "close proximity" to a celebrity in a car

Appearing via video on the at-home edition of 'The Ellen DeGeneres Show', he told the host: “I think it’ll be awhile before we’re singing in a car with anybody.

“We can’t really think of a remote way to do it.

“It really does rely on two people in close proximity so, you know, that’s alright.”

But the 'Gavin and Stacey' star says the day his show can go back to normal will be like "the greatest boom of joy" ever.

He said: "That day, whenever that may be, when it is safe to go out again, and it’s safe for you to go dance around your audience, and it’s safe for me to get in a car with someone. I think it’s going to be the greatest boom of joy we’ve ever experienced.”

James recently had to step down from presenting his nightly talk show "for a few nights" after he underwent minor eye surgery and needed to fully heal up.

He revealed: "I had to have minor surgery on my eye yesterday.

"I am doing well and recovering, but won't be able to film new episode for a few nights.

"Thank you to everyone who has been watching the Late Late Shows from my garage. Stay safe and well everybody."

The 'Late Late Show' had been filming in his garage since the coronavirus pandemic saw production on the chat show close down mid-March, but has continued to get celebrity guests to appear via video call.
