Prince Louis stole the show once again at Trooping the Colour today as he saluted the crowds who came out to watch King Charles' first birthday parade.
After a military ceremony at Horse Guards Parade, the royals gathered on the Buckingham Palace balcony to watch a spectacular RAF flypast, which featured around 70 different aircraft, including the iconic Red Arrows.
It was a much slimmed down family that appeared on the balcony with just working royals only as well as the Prince and Princess of Wales' three children Prince George, Princess Charlotte and Louis.
And as they watched the formation of planes roar overhead, five-year-old Louis could be seen saluting the crowds as well as pulling a range of excitable faces.
One of the highlights of the flypast above Buckingham Palace saw 18 Typhoon fighter jets spelling out the King’s monogram "CR" for Charles Rex.
This prompted much delight from all of the royals, especially Sophie, the Duchess of Edinburgh, who was seen applauding the amazing feat.
Earlier, Charles became the first monarch in more than 30 years to take part in Trooping the Colour on horseback in what was his inaugural Birthday Parade.
Charles took the royal salute as Colonel in Chief of the Household Division’s seven regiments during the ceremony, staged on Horse Guards Parade, as members of the royal family and 8,000 spectators watch.
He was joined on horseback by the royal colonels – the Prince of Wales, Colonel, Welsh Guards; the Princess Royal, Gold Stick in Waiting and Colonel of The Blues and Royals; and the Duke of Edinburgh, riding for the first time in his role as Colonel of the 1st Battalion London Guards, formed last year.
Travelling in a carriage were the Queen, who is Colonel of the Grenadier Guards, and the Princess of Wales as Colonel of the Irish Guards, along with Prince George, nine, Princess Charlotte, eight, and five-year-old Prince Louis.
Kate's gorgeous green dress was designed by Andrew Gn, and featured bejewelled a design, while her matching, wide-brimmed green hat was designed by Philip Treacy.
Queen Camilla wore a red silk dress, reflecting the "heritage of the Grenadier guards" because of her new role of colonel of the Grenadier guards, explained BBC Presenter Huw Edwards, as well as a hat by Philip Treacy.
For the outing, Louis looked dapper in a shirt and tie with with his trademark shorts, and as they prepared to leave Horse Guards, Kate could be seen appearing to tell the five-year-old to sit up as she fussed with his tie.
Even BBC commentator Huw Edwards remarked that Kate was "tidying up" Louis before they headed back to the palace for the finale.
Like his younger brother, George was in suit while Charlotte wore a beautiful red and white dress and they eagerly waved to the crowds who had gathered on the Mall, with Louis even tapping his hands along to the music.
During the Trooping ceremony, the King inspected the Guardsmen, in their scarlet tunics and bearskins, standing in two rows on Horse Guards before the colour was trooped.
The massed bands of the Household Division provided musical backing during the day and also taking part was the King’s Troop Royal Horse Artillery who, following the parade, fired a 41-gun salute in Green Park to mark the King’s official birthday – while from the Tower of London the Honourable Artillery Company fired 62 volleys.
