There were many highlights and key moments from Trooping the Colour - one of which includes the adorable moment Princess Charlotte told off her six-year-old little brother, Prince Louis.
The pair were standing on the Buckingham Palace balcony when Charlotte, nine, went into big sister mode and told her younger sibling off for fidgeting.
Royal fans have likened the young Princess to her great-grandmother, the late Queen Elizabeth and compared it to when the monarch told off her grandson Prince William in 2016.
Charlotte's father - who was dressed in his dashing red uniform - was crouching down on the Buckingham Palace balcony and chatting to his brother, Prince Harry, when the Queen gave him a telling off.
Dressed in a bright green ensemble, she could be seen tapping his shoulder before gesturing for him to get up.

A TikTok page posted a video comparing the two moments and enthusiasts of The Firm have said that Charlotte is the 'new Queen' and that she keeps her siblings grounded as the late Queen Elizabeth once did.
Here, Femail has put together all the times Charlotte has kept her older brothers in check during some of the biggest royal events in the diary.
Trooping the Colour 2024
Princess Charlotte appeared to take her role as the older sister very seriously last weekend as she told her younger brother Prince Louis off, not once, but twice during the annual celebration.
The six-year-old Prince was stood on the platform in front of thousands of fans and well-wishers with his arms slightly scrunched ahead of the national anthem.
His older sibling then said: 'Louis put your hands down,' according to lipreader Juliet Sullivan, before she tapped his shoulder to get his attention.
Louis then scrunched up his face before placing his hands down by his side and standing up straight to prepare for the national anthem.
Earlier in the day, the Prince was once again told off by his sister as she ordered him to 'stop' his dancing, whilst standing at a window in the Horse Guards building, so they could watch King Charles inspecting the troops outside.
As Prince George, Charlotte, and Louis waited by the window with their mother Kate, 42, the youngest royal started swaying his hips, much to the apparent chagrin of his older sister.

Charlotte, who has been seen issuing instructions to her brothers during previous royal events, appeared to tell her sibling to 'stop dancing'.
However, he appeared unmoved by the command, and continued showing off his moves.
Meanwhile, their mother the Princess of Wales appeared to smile while watching the interaction between her children, before she regained her previous, more serious demeanour.
Buckingham Palace appearance after the Platinum Jubilee Pageant

Princess Charlotte also took charge of her two brothers during the celebrations for the late Queen's Platinum Jubilee two years ago.
The royal stood on the Buckingham Palace balcony with her parents the Prince and Princess of Wales and siblings Prince Louis and Prince George.
However, she noticed that her older brother, who is second in line to the throne, had his arms up on the ledge rather than by his side and appeared to be fidgeting.
George then placed his arms down by his side before standing up straight as the national anthem played and a sea of those dressed in red, white and blue sang along.
After Charlotte had a word with George, the late Queen then appeared to turn to him and also say something about him putting his arms down.
The Queen and Princess Charlotte also seemed to be in sync, as they both waved to thousands of fans standing on the Mall at the same time.

Many enthusiasts of The Firm may remember that Kate had her hands full looking after four-year-old Prince Louis during Platinum Jubilee concert in 2022.
Whilst talented singers and bands such as Queen, Diana Ross, Ella Eyre and George Ezra played for the royals, Louis was filmed fidgeting and putting his hands in his mouth.
Princess Charlotte sat next to her cheeky younger brother Prince Louis for the duration of the concert.
This meant that Kate had some help from her only daughter, who was seven years old at the time, who pulled Louis' arm down from out of his mouth to stop him from sucking his fingers.
She then appears to brandish her fist at her younger brother, perhaps warning him against sucking his fingers again.
At this point, their mother, who was known as the Duchess of Cambridge at the time, stepped in, and whispered something to Charlotte.
Louis then went on to mock his older sister, and brandished his own fist in the same way, before his mother gently pushed his arm back onto his lap.

During the four-day celebration of the late Queen's Platinum Jubilee, Princess Charlotte, Prince Louis, Prince George, their mother Kate and Camilla rode in a carriage down the Mall, ahead of the Trooping the Colour.
Both Charlotte and Louis were filmed waving to fans, but the young Prince got a little carried away with his signature 'window wiper' wave.
As the youngest Wales child waves enthusiastically, Charlotte pushes his hand down. She then says something to him, seemingly telling him to stop waving.
Once again unbothered by the stern words, Louis almost immediately starts waving at the assembled crowds once more.
