Prince Louis just made his first public debut at Trooping the Colour. And it couldn’t be any more perfect.
Shortly before the one-year-old royal made his first balcony appearance, he was spotted scowling from the windows of Buckingham Palace with his siblings.
Princess Charlotte and Prince George were showing younger brother Prince Louis the royal ropes!
And it seemed that William and Kate’s youngest child was not overly impressed with today’s Trooping the Colour.
Little Louis was photographed making an adorably grumpy cameo from the window with his sister Charlotte.
However, Louis lightened up his mood quickly and followed his sister, waving and excitedly pointing at the growing crowds.
Prince George also joined them pressing his face against the window before heading out onto the balcony to watch the flypast.
For the celebration, Louis was dressed in white and blue, sweetly coordinated with Princess Charlotte and Prince George.
Although Louis turned one just a month ago, he was expected to make his debut at Trooping this year. He is around the as Charlotte was during her first appearance at Trooping the Colour.
Princess Charlotte was 13 months old when she attended her first Trooping in 2016.
However, Prince George waited a little bit longer. He was nearly two years old when he made his debut.
That’s likely because at 10 months, he was too young for the exciting event the previous year.
Soon after their window appearance, the Cambridge siblings joined their parents, the Duke and Duchess of Cambridge, on the balcony to watch the flypast with the Queen.
Grandfather Prince Charles was also there with the Duchess of Cornwall and uncle Harry and aunt Meghan.
Prince Edward, the Countess of Wessex, Lady Louise Windsor, James, Viscount Severn, Prince Charles, Prince William, Princess Anne, Prince Andrew, Princess Eugenie and Princess Beatrice were just some of the other royals who celebrated the Queen’s birthday.
