Ben Affleck reveals his kids' surprise playdate with Prince George and Princess Charlotte

By Gemma Strong

Despite his best efforts to cross paths with royalty while touring London, Ben Affleck has revealed that it was quite by surprise that his four-year-old son Samuel ended up having a playdate with Prince George and Princess Charlotte. As a guest on The Graham Norton Show, the Hollywood actor opened up about the royal run-in, which came about while his kids were visiting him in London during filming for his upcoming movie, Justice League.

"We did all the sights, and I wanted them to be cultured," he said. "Now, if it was in America – and I hate to admit this – you'd get a VIP pass, you'd get back stage and they would accommodate you. So I got a tour guide thinking this guy will accommodate me, but that wasn't the case!

"He took us in the middle of the street, but we were so far away not only could we not see the guard, we couldn't see the fence! We were surrounded by 50,000 tourists looking for selfie opportunities and we never saw the guards change. It was a disaster!"

Ben – who is also a dad to daughters Violet, ten, and seven-year-old Seraphina with ex Jennifer Garner – continued: "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 one to one of those kids' indoor play parks.

The star said he was the "very last person" to realize that Samuel was playing with the little royals

"It was pretty empty and then I noticed this weird vibe from the other grownups. 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 realize that Prince George and Princess Charlotte were in there playing with my kid. I can now tell him that he got a cold from the King of England!"
