Last week, Prince George and Princess Charlotte stole headlines and hearts around the world with their cheeky antics while watching their parents take to the seas at The King's Cup Regatta.
Especially when a sassy little Charlotte playfully stuck her tongue out at the spectators attending the event.
While the youngsters are typically expected to follow royal protocol, sometimes kids will be kids and will be cheeky every once in a while!
So these are all the times George, who recently turned six-years-old, and four-year-old Charlotte have stolen the show with their cheekiness ...
