The similarities between the royal mother and daughter's mannerisms were first noticed by royal fans last year, when Kate carried out a virtual engagement.
During the video call in February 2021, the Duchess could be seen playing with her ponytail as she spoke to teaching staff.
A royal fan on TikTok, who goes by the account royalfancams, spotted that Kate's daughter Charlotte has adopted the same mannerism. Back in September 2019, the youngster, who was then four, was seen nervously twisting her own ponytail on her first day of school at Thomas's Battersea.

While some fans may say Charlotte is taking after her mother, many agree that she is a miniature version of her great-grandmother, the Queen.

The pair share an uncanny resemblance, especially when looking at photos of the monarch as a young girl, from the shape of their chin and mouth, to the eyes and hair.
Charlotte also displays incredible poise and confidence – a trait shown by the Queen in some of her early childhood photos.

The Princess has also taken up the Queen's favourite hobby, horse riding, with Kate previously revealing that her only daughter is taking riding lessons.
"She emphasised that Charlotte has this passion for horses and although she doesn't echo it, she'll do her best to champion and encourage it," Paralympic gold medallist Natasha Baker once revealed after meeting the Duchess during an official engagement.
