A body language expert says Prince Louis seemed to realize he may have gone a bit too far with something he did to his big brother, Prince George.

Earlier this week on Monday (5 May), the royal family gathered in London to watch the VE Day parade. But it was clear that the youngest child of Prince William and Kate Middleton, Louis, ended up being the center of attention.

At one point during the event, 11-year-old George was seen brushing his hair out of his face. Right after that, Louis copied his brother in an exaggerated way — something that viewers watching at home found hilarious.

Now, body language expert Inbaal Honigman, speaking on behalf of Big Fat Links, has shared her thoughts on why seven-year-old Louis might have realized he went a little overboard.

“Just ahead of the little hair instance, it’s apparent that Prince Louis is looking for something or someone to have fun with,” the expert said. “As he looks to the side, his tongue is in his cheek. This is a cheeky gesture that suggests he’s looking for a game.”

And it looks like he found exactly that.

Inbaal added: “When Prince George flicks his hair, the younger sibling doesn’t miss a beat in copying him.”
