Princess Charlotte looks like a young prince William in side-by-side photos

Like father … like daughter?

Princess Charlotte looks more like her father, Prince William, as she gets older.

But one fan with a keen eye – and memory – dug up an old photo of William from childhood and remarked at the striking resemblance to a picture taken last week when Princess Eugenie was a cousin.

The person posted a side-by-side split of William and his daughter and noted Charlotte also bore a likeness to her grandmother, the late Princess Diana.

"Look at this and tell me they do not look alike (to me)," the post read.

"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! "

Charlotte's looks have been compared constantly to those before her. For the most part, people have commented on her resemblance to the queen.

"She is the spitting image of her great grandmother," said one on Instagram.

Of course, showing royals and their progeny is an age-old game.

Some years ago, a royal photographer for Getty Images spotted an old magazine cover Prince Philip during his sailor days.

The picture sported an uncanny resemblance to another ginger: His grandson, Prince Harry.

The photo was from the 1957 issue of Paris Match magazine. See the similarities for yourself!
