“Matt tried to get David to come on and it was looking hopeful at one point, despite his busy schedule," said a source.

“But David has now announced he’s on a break from his wife and doesn’t think it’s right to be appearing on a British TV show.

“It’s a shame as he would have been a great guest and loads of people would have tuned in to witness the banter between him and Matt.

“The new presenters’ chemistry is improving and the videos have been great, but there hasn’t been one amazing guest compared to who the old hosts used to attract.”

The calibre of celebrity guests during the most recent season off the show, presented by LeBlanc, Rory Reid and Chris Harris, has varied, as had the quality of the interviews themselves.
