Kate Middleton's triumphant return at Trooping the Colour amidst Royal Family drama: "You have to stop doing that. Watch the parade"

Princess Charlotte and Prince Louis exchanged sharp words during the Trooping the Colour parade. It started when the nine-year-old scolded her younger brother.

As previously announced on Saturday’s Trooping the Colour, the long-unseen Kate Middleton appeared. The Duchess, battling cancer, dazzled with her presence as she participated in the King's birthday parade. It was her first public appearance in over six months.

Duchess Kate's children, Prince George, Princess Charlotte, and Prince Louis, also participated in Trooping the Colour.

Although known for his love of mischief, this time, the youngest child of the Prince and Princess of Wales seemed to be exceptionally calm. However, it turns out that this was just an appearance. According to "The Mirror", Louis argued with his older sister. Based on the lip movements of the siblings, the tabloid determined that Charlotte decided to reprimand her six-year-old brother, who was carefree dancing and waving his hands during the ceremonial parade.

You have to stop doing that. Watch the parade - she addressed her younger brother.

Louis did not hide that he would not comply with his sensible sister's words.

I won't - he replied.

Do as you're told - Charlotte didn't give up, this time hearing from her defiant brother a short but firm: Nope.

This is not the first time that the youngest of Kate and William's children has shown his spunk. Prince Louis misbehaved on the balcony of Buckingham Palace (PHOTOS). Will they have trouble with him when he grows up?
