Princess Charlotte's feisty nature has seen her labelled the sassiest of the Cambridge kids.
The seven-year-old is said to be more outspoken than her brothers Prince George and Prince Louis - and could be seen keeping them in check during the Queen's Platinum Jubilee celebrations.
But in one of her rare public appearances alongside her parents, she indulged in some very cheeky behaviour that her left her mum Kate shocked.
It came in 2019, when she attended a sailing regatta on the Isle of Wight alongside her mum, dad Prince William and her grandparents Carole and Michael Middleton.
The then four-year-old and Kate looked out of a window with Kate waving to people that were stood below them.
But rather than follow her mum's lead, Charlotte poked out her tongue.
Kate didn't seem overly impressed when she realised what her daughter was doing.
Even though she was seen smiling broadly and giggling, she leans forward to say something to Charlotte before turning her away from the window to make her stop and ushering her on.
But since that day, Charlotte has made many more public appearance - and at each one of them has charmed the crowds.

And it could be that the youngster gets to go on an exciting outing alongside her dad today to one of the year's biggest sporting events.
It has been reported that she could be at Wembley alongside William to watch to cheer on England's Lionesses in the Euros final against Germany.
The England women's football team recorded an emphatic 4-0 victory over Sweden on Tuesday to book their place in the final, with a capacity crowd expected at the national stadium.
It has been confirmed that William, who is president of the Football Association, will attend the match.
And according to MailOnline, an FA source has said William is considering bringing seven-year-old Charlotte to the big game - although her attendance has not been confirmed.
William recently revealed on a visit to the Lionesses' training camp that his daughter was a keen footballer and loved playing in goal.
He told the team: "Charlotte wanted me to tell you that she’s really good in goal.
“She said, ‘please tell them that.’ Budding star for the future.”
It's unknown if Kate will join her husband at the game as she is due to be at a sailing event in Plymouth today alongside Sir Ben Ainslie.
It has also not been confirmed if nine-year-old Prince George will be at Wembley for the match either - although he did take in the men's Euro final when England suffered a heartbreaking defeat to Italy last July.
