Royal experts have offered the public a sneak peek inside the life of the Royal Family’s ‘secret weapon’ as she approaches her 10th birthday tomorrow.
Insiders revealed how Princess Charlotte, the second child of the Prince and Princess of Wales, is the ‘boss of the family’ and isn’t afraid to speak her mind.
With her cheeky yet sassy personality, the young princess has often been seen keeping her brothers in line, playfully cringing at her parents’ public displays of affection, and stylishly coordinating outfits with her most fashionable relatives.
Royal historian Marlene Koenig told US Weekly ‘Charlotte rules the roost’ at Adelaide Cottage, adding ‘[Kate] describes Charlotte as “independent and the one in charge.”‘
It comes after last year her father Prince William revealed how the straight-talking youngster made him shave off his beard when she disapproved.
According to the prince, his daughter burst into ‘floods of tears’ after seeing his new look for the first time.
And, in June 2024, Charlotte appeared to help her mother, the Princess of Wales, keep her younger brother in check during Trooping the Colour.
Louis, 7, appeared bored during the long, formal event and was seen scrunching his face, playing with curtains and yawning.

But the youngster perked up when the bagpipes started playing during the Horse Guard Parade, shaking his hips in time to the music from the balcony of the Major General’s Office.
According to lip reader Nicola Hickling, the princess, nine, scolded her dancing brother, and said: ‘You have to stop doing that. Watch the parade’, to which he bluntly replied: ‘I won’t’.
Koenig predicts the princess will be carrying out royal engagements when she turns 18 and believes she will be ‘the secret weapon for the royal family.’
But, she also stressed how Charlotte’s parents won’t rush her into her royal duties before she’s ready and want to let her enjoy being a child for as long as possible.
Beneath the grandeur and formalities Princess Charlotte and her siblings, Prince George, 11, and Prince Louis, 7, are just like other children.
Whether it’s eating pizza, blowing raspberries or getting animated over the football, the trio are as ‘normal’ as their gilded circumstances will allow.
In 2023 Prince George , Princess Charlotte and Prince Louis delighted royal fans when they made a surprise appearance at the Big Help Out event in Slough.

Last year Charlotte’s father Prince William revealed how the straight-talking youngster made him shave off his beard when she didn’t approve. According to the prince, his daughter burst into ‘floods of tears’ after seeing his new look for the first time

The Prince and Princess of Wales surprised volunteers at a local Scouts headquarters when they arrived with their children in tow.
Following on from the Coronation concert on May 7, the family spent hours renovating some Scouts huts for local members to use.
Afterwards, clips from the family’s day out were posted on social media – and fans were in awe of how George, Charlotte and Louis seemed like any other ‘normal kids’ their age.
The Daily Mail’s royal editor Rebecca English accompanied the family to the Scouts base and shared a heartwarming clip of Prince Louis, five, happily digging into a smore.
As the Princess of Wales assembled Louis’ snack for him, Princess Charlotte was seen enjoying hers in the background.
However, eagle-eyed royal fans noticed that Princess Charlotte accidentally dropped some of her biscuit on the grass behind her brother.

The video – which has amassed over 68,000 views – shows the couple’s second child crouching down to grab the piece she had dropped.
As she watched her little brother being given his sweet treat, Charlotte then discreetly popped the biscuit in her mouth.
Although Louis’ animated reaction to his smore was the focus of the clip, royal fans pointed out how Charlotte had followed the ‘five second rule’ in the comments.
One replied: ‘[He]s gorgeous but did anyone notice what his sister did in the background?
‘When she bit her biscuit a piece fell on the grass, she quickly picked it up. After a couple of seconds, it went in her mouth. Love! Kids are all the same.’
Another added: ‘Yes, demonstrating that even royal children follow the five second rule!’
‘Yes I did,’ a third wrote. ‘[They’re] just normal kids like others.’
What’s more, another royal fan captured footage of Kate and William’s three children piling into a black 4×4 to head home after the engagement had ended.
The adorable seven-second clip shows Charlotte rushing to open the door first to bag a window seat.
Following close behind her, Prince Louis is seen still happily tucking into some marshmallows.
Allowing his siblings to get in first, Prince George, nine at the time, then takes a step back so he can rearrange his hair – using the car window as a mirror.
