Thousands of royal fans are expected to travel to London to celebrate the King's official birthday this weekend (14 June) - but it was another royal that stole the show at last year's event.
Prince Louis, seven, has been an icon since the moment he came out of the womb - always offering hilarious moments during royal engagements.
And with thousands of spectators expected to flood the Mall to celebrate the beginning of King Charles' birthday celebrations this weekend, fans are hopeful they'll another glimpse of the comedic young prince.
The day usually begins with a military event and procession, followed by the famous balcony appearance from the royals and, of course, the RAF flypast.

Trooping the Colour has marked the official birthday of the King or Queen for over 260 years, and it's an event that has numerous moving parts.
The monarch always has two birthdays, and the procession this weekend does not celebrate King Charles' actual date of birth - which falls on 14 November.
It will be his third Trooping the Colour as the monarch, but he hasn't always been the centre of attention during the special day.
The 2024 event saw Prince Louis and his siblings - Prince George, 11, and Princess Charlotte, 10 - join their parents on the balcony of Buckingham Palace.

But there wasn't just one sweet moment between the youngest Wales and his parents - there were plenty to enjoy.
Plane excitement
While on the balcony of the Palace, Louis shared a sweet moment with his parents.

He watched in awe as a flyover passed by, and appeared completely amazed by the red, white and blue smoke erupting from the jets.
According to lip reader Gaby Lane, Louis turned to his dad and said: “Papa, Papa, Papa, look at all that colour!”
Proud mum Kate smiled at her youngest son and told him the planes had 'dispersed', Lane told The Sun.
Sweet sibling moment
Louis interacted with his older sister Charlotte throughout Trooping the Colour, though the older sibling was looked to be ensuring her younger brother was on his best behaviour.

According to Lane, Charlotte told Louis to 'put your hands down' during the national anthem.
Charlotte's orders
The Princess of Wales stood with her three children at Horse Guards Parade, watching the proceedings for the King's birthday go on.

Louis appeared to be enjoying himself as he danced along during the march of the Scots Guards to Highland Laddie.
Charlotte, on the other hand, was less than impressed.
Expert lip reader Nicola Hickling claimed Charlotte told off Louis, telling him: "You have to stop doing that. Watch the parade."
Louis was having none of it though, as he defiantly responded: "I won't," to which Charlotte apparently sternly told him: "Do as you're told."
Hickling told The Mirror that Louis then simply responded: "Nope."
Chatting to mum
The young prince shared a sweet moment with Kate as they travelled down the Mall together in a horse-drawn carriage.
Louis was astonished by the amount of people who had gathered for the royal event, and pointed out the crowds to the Princess of Wales.
Lane told The Sun that Louis said: "Look over there ma."
“Right, look at that,” Kate replied, according to Lane.
How cute!
