Eddie Redmayne has seen Prince William's privates.
The 34-year-old actor is old school friends with the royal as they both boarded together at the highly regarded Eton College in Windsor, England, and has admitted to having both witnessed the prince, also 34, drunk as well as having seen Will's willy.
Although the 'Fantastic Beasts and Where to Find Them' star didn't divulge any details, when 'Watch What Happens Live' host Andy Cohen asked him if he had ever caught a glimpse of the future King's private parts, Eddie said: "Yes."
And the star gave the same answer when asked if he had ever got drunk with the royal air ambulance pilot - who is currently second in line to the throne.
'The Theory of Everything' actor - who has five-month-old daughter Iris with his wife Hannah Bagshawe - also played on Eton College's rugby team alongside Prince William, and said his friend's reputation gave the rest of the team an easy ride.
He said: "The thing about playing rugby with Prince William is it was great for us, but you would go and want to play but all the people from the other schools would want to tackle him because they could go home and tell their families they tackled Prince William; so we were sort of running around with no-one on us."
And Eddie has revealed he found it interesting watching his fellow school friends "suck up" to William and his bodyguards.
He said: "I do remember that you would go out and the rugby pitches would be quite far away, and he had bodyguards all over the place and they would drive.
"So there would always be a race to see who suck up to him and bodyguards the most so that they could get a lift to the rugby pitches and back."
Meanwhile the actor says he recently caught up with William and his wife the Duchess of Cambridge Kate Middleton - with whom he shares two children, Prince George, three, and Princess Charlotte, 18 months - at a "charity event".
Eddie added: "I saw him at a charity event and he was on very good form. We bonded over newborn children so felt grown up and old."
