This is apparently what Princess Charlotte will look like when she's 18 years old ...

We still can't believe Princess Charlotte turned four-years-old this week!

The young royal continues to capture hearts around the world with her super cute looks.

But while the princess may only be a preschooler, technology has already captured how she might look when she's 18 ...

Spoiler alert: she’s going to be stunning.

American forensic computer age progression experts Phojoe created the image.

“Like her mother, she is likely to have a lower lip that is noticeably fuller than the upper,” said Phojoe’s Jovey Mae Hayes.

“That will give her smile a warm and enigmatic quality at the same time.

“Her paternal grandmother had similar lips too, so there could well be more and more of a ghost-like image of Diana as time passes.”

The experts say that Charlotte “has a genetic propensity to become a truly beautiful young woman”, and will likely be “tall and athletic”.

Guess we’ll be waiting until 2033 to see just how accurate this picture is!
