The Duke of Cambridge has revealed his wife Kate is a "huge fan" of BBC’s Strictly Come Dancing.
Prince William’s comments came as he met the show’s head judge Shirley Ballas and host Claudia Winkleman at a star-studded gala.
“Why does Claudia never dance?!” he asked. “I’m too creaky!” she replied, giggling.
Speaking at an event for Centrepoint on Wednesday, ambassador for the homelessness charity Ballas asked William if he watched Strictly.
“I have watched the show a couple of times...” he said, adding: “Catherine is a huge fan and my mother-in-law loves it.”
Centrepoint was one of the first patronages William took on in 2005, after he’d visited many projects with mother Princess Diana.
The Duke has been a major supporter, camping out overnight on the street, making numerous private visits and always championing the young people the charity supports.
William, in a green velvet jacket, black bow tie and trousers, was complimented on his sartorial elegance by pop singer Rita Ora.
“I love your suit” she gushed. “Well, you’ve got to get it out occasionally!” he said.
To much laughter, a Centrepoint staffer told him he looked “very urban”.
William told the group, which included those who had been helped by the charity as well as staff:
“Tonight is a celebration of all the things you guys have done all the challenges you’ve overcome.
“You guys tell me how amazing it is, getting back out there and feeling part of the community is so important.”
In a speech, William said: “Centrepoint is one of the first charities of which I became patron.
“I chose to do that because visiting Centrepoint services with my mother made such a lasting impression on me as a child.
“And it still makes a lasting impression on me today.”
The gala, at the Round House in Camden, London, celebrated 50 years of the homelessness charity.
Guests, including Princess Beatrice, celebrated those helped by the charity and raised thousands of pounds last night to help change the story for homeless young people.
In his speech William praised Centrepoint for providing homeless young people with accommodation, health support and life skills to get them back into education, training and employment.
But he said: “I hope that Centrepoint will not need to be around in another 50 years.
“It’s upsetting that in 2019 we have still not managed to end youth homelessness.”
