Princess Charlotte has not just inherited her maturity from her late great-grandmother, Queen Elizabeth II, but also the ability to entertain with a humorous skill, a royal expert has claimed.

Royal expert, Phil Dampier, has told Hello! Magazine, the young princess also has a "kind soul" but is also known for being "feisty". He said: "Winston Churchill once said of Queen Elizabeth that he had never seen such maturity in a child so young, and Charlotte seems to have inherited that trait from her great-grandmother, to whom she bears an uncanny resemblance."

He added: "I'm told that Charlotte has also inherited from the late Queen a brilliant ability to mimic prominent figures. She's a kind soul with a reputation for being feisty and keeping her brothers under control."

The late Queen's dresser, Angela Kelly, once revealed that the monarch is a "great mimic" and "can do all accents" and would even try to do an impression of her own Scouse accent.

Not only does she the young Princess have a striking resemblance to her late great-grandmother, she also appears to have inherited her love of outdoor pursuits. The late Queen loved the countryside and also served in the Auxiliary Territorial Service – the women's branch of the army – during the Second World War.

Charlotte's 10th birthday portrait showed her in a camouflage jacket, enjoying the countryside, which is different to previous inages we have seen of her in formal wear or wearing dresses.

Hello! Magazine's royal editor, Emily Nash, said, "I think Charlotte looks a lot like Prince William here, but she also reminds me of the late Queen, who loved spending time out walking, riding and shooting.

"The Princess has clearly inherited that love of being outdoors. Kate has spoken about her own family holidays to the Lake District, so it seems she is continuing that tradition with her children."

Like many girls her age, aside from growing up in the public eye, Charlotte still maintains a love for music and has been enchanted by Taylor Swift.

Prince William took her and brother Prince George, now 11, to see Taylor Swift's show at Wembley Stadium last June. A few months later, on a visit to Cape Town, William wore a friendship bracelet, calling it a "relic" from the concert, that Charlotte had made, spelling out the word "papa".

Charlotte is equally close to her mother and was at her side for one of Kate's first public appearances following her cancer diagnosis, at Wimbledon last July.

Phil also added: "Because Charlotte is the first Princess to be above a living brother in the line of succession, she is growing up with a sense of responsibility. She is great pals with George and Louis, but also a sensitive and clever sister who can guide and help them."
