Princess Charlotte's dream job is incredibly mature for a nine-year-old

Palace sources have revealed that would like to become a nurse after Prince William taught her and her brothers about the important work that NHS staff do.

Although Prince George is set to become king one day, his younger sister Charlotte will likely still hold a major role within the monarchy - but the nine-year-old reportedly has other ideas.

Speaking of the young royal, a Palace source told : "She's obviously just a little kid but still, Will and Kate swelled with pride.

"She's such a caring little girl who also knows what she wants, so they wouldn't be surprised if she does take on as one of her big causes when she's older."

Princess Charlotte - who is currently third in line to the British throne - is expected to take on a role very similar to that of Princess Anne.

Along with her younger brother Prince Louis, Charlotte will one day take on senior positions within the family and is likely to gain important titles.

Despite this, the Prince and Princess of Wales are said to be keen for their two younger children to have more freedom.

Royal expert Camilla Tominey said the royal couple will want Charlotte and Louis to "have their own careers" if they choose to.

When it comes to Louis, who is currently just six years old, Camilla claims that the pair don't want their youngest son to become a "royal hanger-on".

Speaking of Louis and Charlotte, former BBC royal correspondent Jennie Bond previously told OK!: "William and Kate must be acutely aware of the problems for a royal spare.

"They have already shown that they have a different and modern attitude to bringing up royal children and I'm sure they will do everything to make Charlotte and Louis feel every bit as special, loved and valued as George.

"I imagine they will encourage Louis to explore life outside the royal fold... it could be the military, but it could also be working in the charity world or whatever he finds appealing after his education is finished. I'm sure they will encourage him to go to University, which they both enjoyed and where, of course, they found love."
