Richard, 57, and wife Judy, 65, who are one of TV's best-loved couples thanks to their work on ITV's This Morning, have been married for 28 years.
And the reason they've lasted so long? Sex, apparently.
Richard explained to blinkbox Books: “I think relationships can evolve to a point in old age where sex becomes less important - but I am 58, not 98.
“In most dynamic marriages, sex is a very important component. You can deny that at your peril.
"One of the reasons that most marriages fail is because there is a growing sexual incompatibility. It has to be an important part of the equation."
"Research shows most happily married people in their 70s and 80s still have a functioning sex life and so they should. It’s one of the most fundamental aspects of humanity.”
Richard Madeley - who has just released his second book, The Way You look Tonight - also revealed that he wants to make like EL James and write his very own version of Fifty Shades Of Grey.
But from the man's perspective.
He added: “I really like writing about women. That is probably from doing 13 years on This Morning which had a 60-70% female audience. So much was clearly angled towards sexuality.
"You couldn’t help over 13 years as a bloke to pick up on all kinds of aspects of what it is to be a woman today. I think I absorbed quite lot.”
We'll definitely keep our eye out for THAT one, Richard!
