Phillip Schofield will interview the Duke of Edinburgh for a new ITV documentary about the royal's charitable work.
Philip will speak to TV's Phillip for the "landmark royal documentary".
The programme - in which the presenter also talks to the Earl and Countess of Wessex about their involvement - will celebrate 60 years of The Duke of Edinburgh's Award, which helps young people.
The This Morning presenter said: "I am hugely excited to be working with The Duke of Edinburgh's Award as it celebrates its 60th anniversary.
"It's a unique opportunity to meet Prince Philip, the charity's founder, and to see first-hand the amazing work that the DofE does with young people all over the world."
Speaking on This Morning, the TV host said that he'd done his own "diamond challenge" - involving a plane - for the documentary.
The award is marking its 60th anniversary with a Diamond Challenge, which is open to applicants of all ages to embark on a "personal challenge" to raise money for the charity.
Phillip revealed: "The first time I met the Duke at a Duke of Edinburgh Awards ceremony, he said to me 'Did you do your DOE award?' and I said 'It wasn't at our school' and he said 'then why the bloody hell are you here then?' I said 'my wife did her gold' and he replied 'well she should be here then!'... He doesn't suffer fools!"
The documentary, with the working title When Phillip Met Prince Philip: 60 Years Of The Duke Of Edinburgh's Award, is being produced by Spun Gold TV, which made When Ant And Dec Met The Prince: 40 Years Of The Prince's Trust.
Peter Westgarth, chief executive of The Duke of Edinburgh's Award, said: "This is a momentous year for The Duke of Edinburgh's Award Charity as we celebrate our Diamond Anniversary, 60 years of transforming the life and work prospects of millions of young people, from all backgrounds and circumstances, in the UK and worldwide.
"The documentary is a fantastic opportunity for us to reflect on these past successes but also to showcase the positive impact of the DofE on today's generation and the potential for generations to come, helping young people to be happy, healthy, socially conscious and more employable.
"We're excited to be able to capture such a pivotal year, give a unique insight into the DofE in 2016 and thank our founder, HRH The Duke of Edinburgh, for setting up what has become the world's leading achievement award for young people."
