Duke and Duchess of Cambridge during BBC Radio One visit

Prince William and his wife Duchess Catherine appeared on the show earlier this year, and during a quiet moment with the 34-year-old royal and the host Scott Mills, which was not aired on the show, William admitted he has always been a fan of the show and loves the game where innuendos are played whilst two people compete to hold in their laughter and a mouthful of water.

Speaking about the unforgettable moment William - who has three-year-old son Prince George and two-year-old daughter Princess Charlotte with his spouse - praised his show, the Radio One DJ said: "William genuinely grew up listening to Radio 1. When we were having a downtime moment on the day, William said: 'By the way, I've listened to you for a very long time.' I said to him: 'I don't think I'm going to be able to top today in terms of interview.' Wills said: 'Oh, come on, you've been to live with David Hasselhoff!' I actually had done that for a show on Sky Living. Then he said: 'I love Innuendo Bingo [a slot on Scott's radio show].'"

However, the 35-year-old royal - who was formerly known as Kate Middleton prior to marrying William - had no idea what the stint was, although William promised to fill her in at a later date.

Scott explained: "Kate asked: 'What's that?' He said: 'I'll explain later, darling.'"

Scott was not only blown away by their presence, and William's confession he is a fan, but also by their generosity.

Scott told The Sun's TV magazine: "I'd also done the LOL-a-thon, a 24-hour event for Comic Relief, just before that, and William said: 'By the way, I texted in and donated to the LOL-a-thon a couple of times.' That was one of the most surreal days of my whole life. They were so lovely."
