The royal couple were greeted by Holly Willoughby and Phillip Schofield who spoke to the Duchess of Cornwall and the Prince of Wales for a special edition of the ITV show.
Charles and Camilla first met ITV CEO Carolyn McCall and Chairman Peter Bazalgette before making their way to This Morning, to celebrate the show’s 30th anniversary in October this year.
All the ITV favourites were on hand to welcome their Royal Highnesses, with Good Morning Britain’s Susanna Reid and Piers Morgan, Lorraine Kelly and Loose Women stars Andrea McLean and Gloria Hunniford swapping studios for the special occasion.
Holly and Phillip then introduced the royals to Friday presenters Eamonn Holmes and Ruth Langsford, who was congratulated by Camilla for her stint on Strictly Come Dancing.
“As a patron to charities headed by both The Prince of Wales and the Duchess of Cornwall, I’m really thrilled to welcome them to the This Morning studio. It’s a fantastic way for us to celebrate our 30th anniversary,” Phillip enthused.
Holly beamed: “It’s been wonderful to welcome Their Royal Highnesses to This Morning. It’s an exciting year for us here, and it’s lovely to share with them some of our highlights.”
Editor Martin Frizell explained: “We also asked them to sign our first ever Visitors’ Book, which is going to be filled with pictures and messages from all our guests as we enter our 30th year.
“We’re going to take photos on a polaroid camera and give the book away to one lucky winner to mark the show’s 30th birthday in October.”
Carolyn McCall, ITV Chief Executive, said: “We were really pleased to host Their Royal Highnesses at ITV as part of the Royal Television Society’s 90th birthday celebrations.
“ITV is very much at the heart of popular culture in the UK and we were delighted that The Prince of Wales and The Duchess of Cornwall were able to get a glimpse behind the scenes at one of the cornerstones of our schedule – the award winning This Morning.
“Their Royal Highnesses also met many members of the cast and crew of our other brilliant Daytime programmes, together with the apprentices that we have working right across the business.”
The list came just moments after Holly and Phillip were live on air downing shots of rum for a special tasting session.
Holly grumbled: “This was a bad idea,” before comically gasping: “I love you!”
“Don’t do it,” Phillip grinned.
This Morning airs weekdays at 10.30am on ITV.
