Prince George and Princess Charlotte had surprise playdate with Ben Affleck's son
With all the treasures money can buy at their disposal, one might think Prince George and Princess Charlotte rarely have cause to venture out in public to play with children their own age.
But not so, it appears, as Ben Affleck discloses how his own son accidentally bumped into them at an indoor soft play area.
Affleck, the actor, told how he had taken his young family to try and spot the Royal family at Buckingham Palace, Windsor Castle and the Tower of London, only to finally encounter Prince George and Princess Charlotte at a playpark.
Appearing on the BBC's Graham Norton Show, he said: "Despite going to Windsor Castle, Tower of London and Buckingham Palace, we didn't see one royal.
"Then when it was raining, I took my youngest [Samuel] to one of those kids' indoor play parks.
"It was pretty empty and then I noticed this weird vibe from the other grown-ups.
"They were all very well dressed and they had earpieces and I thought, 'For a kids' place this is tight security.'
"I was the very last person to realise that Prince George and Princess Charlotte were in there playing with my kid."
He added: "I can now tell him that he got a cold from the King of England."
Affleck, 44, has three children with actress Jennifer Garner.
He spent time in London to publicise his latest film The Accountant.
Despite the subject matter, he told Norton: "I'm pushing my luck with my daughter's 5th grade homework.
"The director insisted the numbers were exactly right and I defy any one person to solve the maths in that movie!"
Affleck joined Claire Foy and Matt Smith on the coach as they talked about filming The Crown, as well as David Attenborough and Sting.
The programme will be broadcast on BBC One at 10.35pm on Friday.
