It was the Queen's official birthday today but Prince George stole the show on just his second public appearance.
The toddler joined his parents, the Duke and Duchess of Cambridge, on the balcony at Buckingham Palace to watch the traditional fly-past of aircraft.
George wore a sky-blue shirt and shorts with matching shoes.
He was held by William and waved to the crowd below.
The one-year-old looked up at the aircraft as they roared over the Palace to conclude the pomp and pageantry of the Trooping the Colour ceremony.
It was Kate 's first official engagement since the birth of Princess Charlotte six weeks ago.
She wore a coat by Catherine Walker and hat by Lock and Co.
There was no sign of the young princess.
The Queen's actual birthday was on April 21, when she turned 89. However, her official birthday is always celebrated nationally on the second Saturday in June when the weather is usually reckoned to be more predictable.
The fly-past came at the end of a three-hour extravaganza of pomp and pageantry, with the annual Trooping the Colour celebrations.
Joined by all the senior members of the Royal Family, the Queen inspected 1,100 soldiers of the Household Division at Horse Guards Parade in central London.
She arrived in an Ascot Landau vintage carriage following a short drive down The Mall from Buckingham Palace, accompanied by the Duke of Edinburgh.
She wore a peach and silver dress and coat by Angela Kelly and a matching hat - previously seen at the Diamond Jubilee horse pageant in May 2012.
The Prince of Wales, who is Colonel of the Welsh Guards, the Princess Royal, who is Colonel of the Blues and Royals, and the Duke of Cambridge, Colonel of the Irish Guards, were all on horseback for the ceremony.
Kate arrived in a coach alongside Prince Harry and the Duchess of Cornwall. Guests included Prime Minister David Cameron and wife Samantha.
The Colour being paraded on Horse Guards this year was the flag of the 1st Battalion Welsh Guards.
The Prince of Wales Company, 1st Battalion Welsh Guards trooped the Queen's Colour presented to them by the monarch at Windsor Castle in April.
Four of the five Foot Guards regiments of the Household Division - the Welsh Guards, Grenadier Guards, Scots Guards and the Coldstream Guards - marched in the parade wearing bearskin hats and red tunics.
The Household Division Bands and Corps of Drums also took part, as did the King's Troop Royal Horse Artillery.
Trooping the Colour originated from traditional preparations for battle.
Colours, or flags, were carried, or ''trooped'', down the rank so that they could be seen and recognised by the soldiers.
In the 18th century, guards from the royal palaces assembled daily on Horse Guards to ''troop the colours'' and in 1748 it was announced that the parade would also mark the Sovereign's official birthday.
Following the parade, The King's Troop Royal Horse Artillery fired a 41-gun salute in Green Park to mark the Queen's official birthday.
Some 31 aircraft had been lined up to take part in the finale, including Spitfires and Hurricanes. But the poor weather meant it was left to the Red Arrows to bring the curtain down on the event.
