Kate Middleton's words to Prince Louise on palace balcony revealed

On Saturday, the members of the royal family including King Charles, Queen Camilla, Kate Middleton, Prince William and their three kids made an appearance at the Buckingham Palace balcony during the Trooping the Colour.

In one moment that caught attention Kate Middleton, who was standing alongside the King and Queen along with William and their children Prince George, Princess Charlotte, and Prince Louis, had a firm command for her youngest one.

Louis, known for his cheeky signature cheeky antics, was on his best behaviour during the King’s birthday celebration.

However, a lip reader Jeremy Freeman told Mirror that the Princess of Wales instructed Louis to call attention to the national anthem.

Jeremy said that Kate told Louis, "National anthem. Louis, stand" which led him to straighten his posture and focus on singing the national anthem.

On the other hand, King Charles and Prince William also had a short exchange at the conclusion of RAF flypast.

The lip reader revealed that the Prince of Wales turned to his father Charles and said, "Oh my word, what a day."

"Great theatre," King Charles replied.

It is worth mentioning that upon the conclusion of the King's birthday festivities, the royal family and the Prince and Princess of Wales' official Instagram handles dropped a video showcasing highlights on the day.
