Prince Louis makes adorable debut alongside sweet siblings Prince George and Princess Charlotte

By Meaghan Wray

The Cambridge clan is all together again for Trooping the Colour, and joined by their latest adorable addition, Prince Louis, no less! Making his sweet debut at the annual affair, little Louis looked sweet as pie in the arms of mom Duchess Kate and alongside siblings, Prince George, 5, and four-year-old Princess Charlotte.

Little Louis looked absolutely adorable in the arms of his loving mom, Duchess Kate. The young royal – who waved excitedly at well-wishers down below – looked sweet in a blue-and-white ensemble, sporting a small pair of patent leather shoes, for the occasion.

Charlotte melted hearts the world over with her excited waves as she took her spot on the balcony, while her older brother kept it cool – after all, he's seen a few of these events before! The princess will be joining her big sibling at Thomas's Battersea school this September.

The youngest of the Cambridges joined other senior members of the Royal Family – like the Queen, dad Prince William, the Duke and Duchess of Sussex, Princes Charles and Camilla – for the exciting day celebrating his great-grandma's birthday. Notably absent was baby Archie Harrison, of course, who's much too young to fully enjoy the occasion.

Louis is the youngest of the three Cambridge kids to attend Trooping the Colour for the first time. Given the birthdates of Charlotte and George, more time was needed for them to be a bit older. Louis's older brother was two when he first went, while Charlotte was one when she made her adorable debut, matching in pink with her mom.

Back in May, Prince William and Kate took their three kids on an unofficial outing to the Chelsea Flower Show. The trio enjoyed some time in the sun, playing in the duchess's Back To Nature garden, which boasted a running stream and even a rope swing!
