As London prepares for a wave of royal enthusiasts celebrating the King’s official birthday this weekend, many eyes are once again turning to a younger royal who has quietly become a fan favorite: Prince Louis.

At just seven years old, Prince Louis has built a charming reputation during public appearances — known for his candid reactions, cheeky expressions, and spontaneous remarks that often outshine the formalities of royal events.

This weekend’s Trooping the Colour ceremony, the annual event held in honor of the monarch’s official birthday, is expected to draw large crowds to the Mall. Though King Charles is the reason for the celebration, royal watchers are secretly hoping for another delightful moment from the youngest son of Prince William and Princess Catherine.

A Royal Tradition — With a Twist of Humor

For more than 260 years, Trooping the Colour has marked the sovereign’s ceremonial birthday, complete with military pageantry, a balcony appearance from the Royal Family, and a spectacular RAF flypast. This year marks King Charles’ third time leading the festivities as monarch, but history has shown that he often shares the spotlight — willingly or not.

Last year, Prince Louis made headlines alongside his siblings, Prince George and Princess Charlotte, during the balcony appearance at Buckingham Palace. While the grown-ups maintained their formal poses, Louis couldn’t hide his excitement.

“Papa, Look at All That Colour!”

One of the most memorable moments came during the flypast, as Louis marveled at the colorful trails left by the jets soaring above. According to professional lip reader Gaby Lane, the young prince turned to his father, Prince William, exclaiming: “Papa, Papa, Papa, look at all that colour!”

Princess Kate reportedly responded with a warm smile, gently telling Louis the planes had already “dispersed.” The exchange, though brief, highlighted the sweet bond between the young prince and his parents.
