The 1-year-old son of Kate Middleton and Prince William attended his first official royal event on Saturday.

Prince Louis just had a major milestone!

Kate Middleton and Prince William's 1-year-old son made his first official royal appearance on Saturday on the balcony of Buckingham Palace for the annual Trooping the Colour ceremony. The youngest child of the Duke and Duchess of Cambridge looked precious in a white shirt with blue stitching that perfectly matched his shorts

Louis was also joined by his big brother, 5-year-old Prince George, and sister, 4-year-old Princess Charlotte. Both George and Charlotte made their first Trooping the Colour appearance when they were just a year old. In video shared by Kensington Palace, little Louis and his sister adorably wave to the crowd outside the palace.

The annual event brings together over 1,400 parading soldiers, 200 horses and 400 musicians to honor Queen Elizabeth II's official birthday. The entire royal family, including Meghan Markle and Prince Harry, all stepped out for the special occasion and reunited at the Buckingham Palace balcony.

Last year, George and Savannah made headlines for the silly faces they made while on the balcony with their family.
