Charlotte is third in line to the throne and set, one day, to be Princess Royal, following in the footsteps of her great aunt, Princess Anne, and many think she would be a natural successor to the role.

Because of changes in 2013 to the rules concerning the order of succession that mean male heirs are no longer prioritised above female heirs, Charlotte, born in 2015, became the first British princess to rank above a younger brother.

Her full name is Charlotte Elizabeth Diana, and she was born in the Lindo Wing of St Mary’s Hospital in Paddington, London, at 8.34am on May 2, 2015, weighing a very healthy 8lb 3oz.

At such a young age, she already has a legion of fans, in part thanks to her seemingly effortless decorum on the global stage.

She has already won hearts by frequently taking charge of her brothers at public events, especially her younger sibling, Prince Louis, who turned eight on April 23.

Last week, the couple shared a new photo of the young prince captured by Prince William and the Princess of Wales‘s trusted photographer Matt Porteous during the family’s Easter getaway to Cornwall.

Insiders have previously described Princess Charlotte as the royal family’s ‘secret weapon’, taking on the role of a ‘boss’ at home who is not afraid to speak her mind.

Royal historian Marlene Koenig told US Weekly ‘Charlotte rules the roost’ at Adelaide Cottage in Windsor, adding ‘[Kate] describes Charlotte as ‘independent and the one in charge.’

Last year, her father, William, revealed how the straight-talking youngster made him shave off his beard when she disapproved.

rincess Charlotte’s last public appearance was on Easter Sunday when she joined senior royals for the traditional service at St George’s Chapel in Windsor.

She put on a sweet mother-daughter display with Princess Catherine as they were spotted walking out of the service while holding hands.

They also wore coordinated outfits, with Catherine opting for a cream two-piece suit from Self-Portrait with a brown leather handbag and matching heels.
