Nobody is perfect, but we can all admit that Kate Middleton comes very close.
The Duchess of Cambridge is beautiful, smart, stylish, charitable, as well as a doting mother and wife. Seriously, she's like a real-life Disney Princess (we just need to verify that she can hold a note to confirm our suspicions).
However, while Disney Princesses are made out to seem flawless (they're really not), the same cannot be said about Kate.
You may have never noticed it, but the future queen of England has a scar on the side of her head that is almost always strategically hidden by her hair.
Eagle-eyed royal watchers spotted the three-inch mark back in 2011, and many thought it was a bad hair extension job. Turns out, that is far from the truth (obviously, her hair is perfect without additions).
After much speculation, Kensington Palace decided to clear the air and reveal why Kate had a scar running down the side of her face.
"The scar is related to a childhood operation," a palace spokesperson told E! News at the time.
Although the public was finally given confirmation that the mark was left behind after a medical procedure, people were curious to know why she needed surgery in the first place. The palace declined to offer further comments on the matter, saying it was "private."
Some royal sources have said that it was a "serious" operation. Others, like London-based consultant surgeon John Scurr, are convinced that it wasn't a big deal.
"I really doubt it was any serious medical condition and I would say it is as a result of an arteriovenous malformation "� a birthmark "� being removed," he told The Sun.
Neither Kate nor her family have addressed the rumors, and we don't blame them as they don't owe the public an explanation of her medical history.
The mother-of-three isn't the only royal with a noticeable facial scar. Her husband, Prince William, also has what he calls a "Harry Potter scar" on the left side of his forehead. Considering it's a much bigger blemish than his wife's, it's surprising that people have been blind to it for so long.
While Kate hasn't acknowledged her scar in public, the Duke of Cambridge doesn't keep the story behind his a secret. He revealed in a 2009 interview that it happened after he got hit by a golf club when he was 13.
"I call it [my Harry Potter scar] because it glows sometimes and some people notice it"�other times they don't notice it at all," William explained. "I got hit by a golf club when I was playing golf with a friend of mine. We were on a putting green and the next thing you know there was a seven-iron and it came out of nowhere and it hit me in the head."
Also, don't you think it's interesting how both William and Kate have similar scars on the same side of their faces? This just reaffirms what we've known all this time: they're definitely made for each other.
