The 65-year-old 'X Factor' judge has reportedly been approached numerous times to join the 'Good Morning Britain' host for an in depth interview, but he has repeatedly snubbed him because he has "no interest" in doing it.

A source told The Sun newspaper: "Louis has no interest in being grilled by Piers on the show despite their numerous offers.

"He is quite a private person behind closed doors and wants to keep things that way.

"As a show, Louis enjoys watching it but you won't see him on it anytime soon."

The show - which is currently airing its fifteenth season - has featured a number of high-brow celebrities including Kim Cattrall, Pamela Anderson, Jim Davidson, Ivana Trump and Caitlyn Jenner.

During Piers' interview with Caitlyn - who was formerly known as Olympian Bruce Jenner before undergoing gender reassignment surgery - he was called out for being "disrespectful" to the trans community.

During the Q&A session, Piers presented Caitlyn with an old doll of her as Olympic gold medallist athlete Bruce which was released in the wake of his 1976 decathlon victory at the Montreal Olympic Games.

Piers then asked: "How does your physique compare now. Obviously certain areas?"

Caitlyn replied: "See you made a comment there and that is why you would get in trouble. OK? You just said, 'Certain areas?' That to a trans person is disrespectful.

"It is not funny. It is life. It is a very serious part of my life. I take that very seriously and so out of respect to myself and the community it is not something that you joke about. It is something as I said before ... this is serious. You can die over this issue. It is not a joke."
