ITV has commissioned a pilot for a new reality chat show hybrid, 24 Hours With...

In the show - to air later this year - a celebrity will be locked in a room with host Jamie Campbell and interviewed non-stop for 24 hours.

"It is the absolute opposite of a typical celebrity interview - no hype, just real chat and a chance to get to know a star," said Layla Sabih, ITV's head of reality. "We're taking the essence of reality TV and merging it for the first time with the chat show genre."
