Ahead of Saturday's festivities, King Charles III also honored a handful of celebrities and public figures, including David Beckham, Gary Oldman and Elaine Paige.

King Charles and Queen Camilla led the Royal Family at Trooping the Colour outside Buckingham Palace today. The 76-year-old monarch and his 77-year-old wife were seen beaming and waving from the balcony at well-wishers who had gathered outside the iconic London landmark.

Saturday’s event may be steeped in pomp and pageantry, but it carries deeper meaning for the British monarchy.

The young Princess attended the event alongside her family and paid tribute to her late great-grandmother along the way.
