Most royal encounters come with bows and curtsies, but for Ben Affleck's 4-year-old son, Samuel, a brush with Prince George and Princess Charlotte led to a case of the sniffles — and bragging rights.

In an interview that set to air on Friday's "Graham Norton Show," the actor explained that the royal run-in at an indoor play park in London was completely unexpected.

"It was pretty empty, and then I noticed this weird vibe from the other grownups," the "Batman v Superman" star said. "They were all very well dressed and had earpieces, and I thought, 'For a kids’ place, this is tight security!'

But it all made sense when he finally figured out that his son was having fun with a couple of high-profile tykes.

"I was the very last person to realize that Prince George and Princess Charlotte were in there playing with my kid," Affleck admitted.

When it was all over, Samuel, who's the youngest of Affleck's three children with Jennifer Garner, had more than a good time. He also had a cold.

"I can now tell him that he got a cold from the king of England!” Affleck boasted.
