The Queen celebrated her official birthday at a low-key Trooping the Colour ceremony at Windsor Castle on Saturday, but despite the pared-back ceremony, there was one moment when the monarch showed a look of sheer delight.

The Queen's face lit up during the RAF flypast at the end of the ceremony, as she gazed into the bright blue skies to see the iconic red, white and blue streams of smoke left by the jets.

The fly-past over Windsor Castle was a spectacular sight, and although traditionally the royals would gather on the balcony of Buckingham Palace to watch together, Her Majesty still seemed to enjoy the show.
On parade in front of the Queen in the bright summer sunshine was an array of socially distanced Guardsmen, mounted Troopers and the King's Troop Royal Horse Artillery.

The Queen was also spotted tapping her feet in time to the music, as the band played and she soaked up the atmosphere.

The Queen wore a grey jacquard coat with lemon flowers with a matching hat by Angela Kelly, and she wore this same attire for the Official State Opening earlier this year.
Looking radiant, she paired her stylish outfit with a striking blue brooch, which was a nod to the Queen Mother. The Aquamarine Art Deco Brooch was handed down by her late mother and the Queen has worn it on a few occasions since. Royal fans have seen it at Royal Ascot in 2014 and at Buckingham Palace's garden party in 2017.

The Queen also seemed in very good spirits on Friday at the G7 Summit Big Lunch where she insisted on borrowing a ceremonial sword to cut a cake, which prompted giggles from the Duchesses of Cornwall and Cambridge.
