Fans of the royal family are constantly seen gushing over Princess Charlotte's resemblance to her grandmother Princess Diana, but she's not the only person the little one shares a resemblance with. A lot of royal watchers, after close inspection, have noticed the striking similarities between the 3-year-old and her father Prince William, the Duke of Cambridge.

An Instagram fan account recently posted a childhood picture of Prince William at the age of ten go-karting at Buckmore Park 'Playscape.' The photo resulted in people comparing a young William's smile to that of his daughter Charlotte, reported the Daily Mail.

The same account, which goes by the name Tea Time With the Cambridges, posted a side-by-side photo of Charlotte at Princess Eugenie's wedding last week, along with Prince William's picture. The image was captioned: "Look at this and tell me they don’t look alike 😂 (to me) Ever since she was little Charlotte has had the 'Diana Smirk' which William obviously got from Diana and Charlotte got from her daddy! She is definitely daddy’s little lookalike and daddy’s little girl! 💕! "

The picture instantly caught the eye of a lot of royal fans, and in no time, it received over 14,000 likes. Quite a lot of royal watchers agreed both William and Charlotte looked somewhat like "twins." One user commented: "Wow!!!! Now that’s twinning! She is the spitting image of her father in this photo." Agreeing with the previous person, another added: "Wow she sure does look like her daddy here!!!" A third wrote: "mate they look identical."

Few people would have noticed Princess Charlotte's picture was the same one through which a lot of royal fans had speculated that the young royal was slowly and steadily, forming a stance similar to her great-grandmother, the Queen. The toddler was seen resting her hands together on her lap in the picture, just the way the Queen folded hers during the family portrait.

Sharing side-by-side photographs of Charlotte with the Queen, an Instagram fan account posted: "Charlotte taking inspiration from the boss, her great-grandmother The Queen." Fans who noticed the resemblance commented, "She looks so much like her great grandma," while another user added, "Princess Charlotte real(ly) resembles the Queen."
