At just four years old, Princess Charlotte has already won the hearts of the people, from her adorable handbags to her cheeky interactions with the press.
The charming royal is already attending royal tours and official events with her parents, Prince William and Kate Middleton.
The four-year-old is officially known as Princess Charlotte of Cambridge, a title she inherited at birth due to being a direct descendant of the heir to the throne.
However, according to Express, a royal rule may mean that Princess Charlotte is likely to adopt a new royal title, only possible with the death of a senior family member – namely, Princess Anne.
Being the only daughter of William and Kate, Charlotte may be the next royal to hold the title of Princess Royal.

The royal title can only be held by a member of the royal family at a time, much like a King or Queen.
Queen Elizabeth II’s daughter Princess Anne currently holds the title of Princess Royal, which means that the granddaughter of Prince Charles can only inherit the title upon the Princess Royal’s death.
Before Princess Anne, Mary, Countess of Harewood was Princess Royal, and the royal title was relinquished upon her death in 1965.
The title of Princess Royal is usually given to the eldest daughter of the monarch, and came into the British royal protocol when Queen Henrietta Maria (1609–1669) wished to imitate the way the eldest daughter of the King of France was styled “Madame Royale”.
However, this isn’t the only royal title that Princess Charlotte might be able to hold.
On a special occasion, The Queen will gift royal family members another title alongside Prince and Princess.
For example, Prince Harry and Meghan Markle became the Duke and Duchess of Sussex following their wedding in 2018, and Charlotte’s parents, hold titles as the Duke and Duchess of Cambridge.
Much like her father and uncle, Princess Charlotte could also hold a Dukedom when she is married.

She is not guaranteed the royal title, however, as the decision is up to the Queen.
For instance, Queen Elizabeth denied her son, Prince Edward, a Dukedom after his marriage to Sophie Rhys-Jones in 1999.
Instead, he was made the Earl of Wessex and his wife Sophie became the Countess of Wessex.
However, it is likely he will become Duke of Edinburgh when his father, Prince Philip, dies.
