#TroopingTheColour may be a celebration of King Charles, but his grandchildren, Prince George, Princess Charlotte and Prince Louis, stole the show at the event! Following tradition, the royal siblings joined their parents, Prince William and Kate Middleton, as well as the King and Queen Camilla on the balcony of Buckingham Palace to wave to onlookers and watch the flypast of the Royal Air Force's Red Arrows.
