Trooping the Colour: Prince George, Princess Charlotte, Prince Louis's balcony moments

Trooping the Colour is the celebration of King Charles’ official birthday, but his grandkids, Prince George, Princess Charlotte, and Prince Louis, always steal the show.

The three kids joined their parents, Prince William and Kate Middleton, and the King and Queen Camilla on the balcony of Buckingham Palace to watch the flypast and wave to the public.

The siblings watched the Royal Air Force's Red Arrows flypast in the Royal Family’s balcony appearance, which serves as the grand finale of the annual Trooping the Colour celebration in London.

When the flypast ended, Prince Louis smiled and waved once again at the onlookers. Charlotte also turned to look at the public. The trio then left with their parents.

Earlier in the day, the kids arrived in a horse-drawn carriage with their mother, Princess Kate. All three waved and smiled happily, with Louis debuting new front teeth after his toothless look at his birthday in April.

Charlotte twined with Princess Kate in an aqua colored dress and completed her look with a diamond horseshoe-shaped brooch that she received as a gift from the late Queen Elizabeth. Prince George and Prince Louis matched with their Prince William in suits and red ties.
