They might live in palaces and have a diary full of public appearances, but it turns out the royal family likes the same TV shows as us!

Prince William is about to make his Graham Norton Show debut, and on the pre-recorded episode, he chats about everything from his Earthshot Prize to his family’s favourite way to relax together.

The Prince of Wales told Irish host Graham that he and his two youngest children, Princess Charlotte and Prince Louis, cannot get enough of The Traitors.

Prince William even revealed that he touched paranoid faithful Ross Kemp ‘to see what reaction I got from him.’

The EastEnders star had been on alert about being murdered in plain sight through touch since the first episode of the BBC One series.

The paranoia proved justified in Thursday’s episode, when he was indeed murdered in plain sight by traitors James Acaster and Maya Jama.

But instead of touch, he was murdered by yawning and inhaling a poisoned perfume.

Discussing The Traitors during a surprise appearance on The Graham Norton Show, William said: ‘I love it, the family loves it. Charlotte and Louis are obsessed with it. It’s really good telly.

‘I saw Ross Kemp the day after the first episode, and I couldn’t help but try – in the most appropriate way – to touch him to see what reaction I got from him. Turns out he was really jumpy!’

Asked how he switches off, he said: ‘It is music and film. I love getting immersed in deep-thinking films. I like action films too, but I like something a bit different.

‘I’m a big fan of everything Christopher Nolan does. His films are fantastic – The Dark Knight series is psychologically dark and deep, and I absolutely love that.

‘He takes concepts that are completely out there and makes them incredibly entertaining.’

William joined Cate Blanchett, Robert Irwin and Hannah Waddingham on the chat show to gasps from the audience to speak about the environmental award, which connects all four guests.

Blanchett is an Earthshot Prize council member, Irwin is a global ambassador for the prize, and Waddingham hosted the 2023 Earthshot awards in Singapore.
