She is often described as the most outspoken and determined of all of the Duke and Duchess of Cambridge's children.
And Princess Charlotte's mum Kate once remarked that her only daughter is the boss of the Cambridge household.
So it's no surprise that in the few public appearances that she's made, her strong personality has really shone through.
And one of those times came when she was greeting royal fans alongside her mum at Sandringham on Christmas Day 2019.
When Charlotte emerged from church at Sandringham on that day, she was presented with a beautiful bunch of white roses by a well-wisher.
Royal aides are then usually passed the flowers to carry so the royal can keep their hands free and talk to other well-wishers.
But it appeared that Charlotte had clearly taken a liking to the blooms and wasn't ready to give them up.
So when an aide offered to carry them, she shook her head and refused to let them go.
She then clutched the flowers as she walked back to Sandringham House with the rest of the royals.

Royal expert Katie Nicholl previously told the Mirror: "Charlotte is the most buoyant and outgoing of the three Cambridge children.
"It’s that strength of character that will stand her in good stead when she’s older."
And it seems that when she is older, her dad Prince William will take the throne making him King and her mum Kate Queen.
And when this happens it seems that Charlotte will be in line for a unique royal title - even grander than her current one.
That title is Princess Royal, which is traditionally bestowed on the eldest daughter of the monarch.
The title was first introduced to mimic the French royal title of Madame Royale back in the 1600s.
The current Princess Royal is the Queen’s only daughter Princess Anne, who was given the title in 1987.
However, royal expert and author of Prince Harry :The Inside Story, Duncan Larcombe, told TownandCountrymag.com: “The title of Princess Royal is traditionally bestowed on the eldest daughter of the monarch.
"It is a title that remains for life, so Princess Charlotte will have to wait at least until the death of the current Princess Royal."
