Her Majesty was celebrated on Saturday at the Trooping the Colour parade, an event which has marked the official birthday of the British Sovereign for over 260 years.
The queen, who turned 92 on April 21, looked regal in a vibrant blue look, which she paired with a matching hat.
Queen Elizabeth, who recently underwent a successful cataract operation, arrived in an open Ascot Landau carriage to Horse Guards Parade in Whitehall from her home at Buckingham Palace.
Harry and William were in military dress uniforms.
Her husband, the Duke of Edinburgh, attended the event with her previous year, but was absent today. His absence had nothing to do with his recent hip surgery. See PA story ROYAL Wedding. He will celebrate his 97th birthday Sunday.
Meghan fussed with her loose hair and seemed to be troubled by her Philip Treacy hat. While Harry smiled and waved, she looked a bit overwhelmed as she surveyed the huge crowds lining the route.
Meghan, Harry and the other members of the royal family took their place in Wellington's former office which overlooks the parade ground.
At 1pm, the royals gathered on the balcony for the RAF flypast featuring 23 modern and historic planes, Meghan taking centre stage.
Prince William and Kate Middleton's third child, Prince Louis, was noticeably absent from the event. She is the Queen's eldest great grandchild.
