Videos posted online show the 6-year-old prince casually dancing in the window of Horse Guards Parade as his sister Princess Charlotte and mother Princess Kate smile at one point as they wait to walks out with the Royal Family on the balcony of Buckingham Palace.

Prince Louis was then seen gaping both at the Palace window and while with his family on the Buckingham Palace balcony.

Closely followed by fans and the press, the little prince of the Royal Family is seen naively playing with curtain cords during the Trooping The Color parade.

And during the singing of the anthem, Princess Charlotte draws the attention of Prince Louis, who would not have been in the right position.

Much to the delight of fans, who have flooded social media with images of Prince Louis, in one picture during the parade, he was snapped appearing to struggle to open a window next to the Duchess of Edinburgh.

And in another picture, Prince William touches his little one's ears, even while making a funny face.

Princess Kate made her first public appearance this year after being diagnosed with cancer, accompanied by her three children, Prince George, Princess Charlotte and Prince Louis, to attend the King's birthday parade.

Prince Louis has become a favorite among royal fans after a series of “hilarious” appearances at public events.

Last year, Prince Louis stole the show at King Charles III's first Trooping the Color since becoming monarch. During the parade, he was photographed pinching his nose, making funny faces and playing with his hair as he made his way to the military parade commemorating his grandfather's first “official” birthday as sovereign.

And at Louis' first appearance at the Trooping the Color ceremony in 2022, Queen Elizabeth's last birthday parade, the youngest prince was seen covering his ears and shouting during the RAF parade.

Even at the coronation ceremony of Charles, last month, the little one did not sit properly.

On the way to Westminster Abbey, Louis pressed his face to the carriage window as he waved to fans who had gathered for the historic moment, then was seen yawning widely. During the ceremony, Louis appeared distracted by something on the ceiling, while his older sister Charlotte leaned over to see what he was gesturing at.

The Trooping the Color ceremony is a royal tradition that dates back to the 18th century, when it was first performed during the reign of King Charles II in 1748.
