One Direction fans across the world know that each of the guys is swoon-worthy, but now science is totally backing up claims as to why so many Directioners are obsessed with everything about Harry Styles.

Yes, science totally has a fangirl’s back on this one. A study was published by The Centre For Advanced Facial Cosmetic and Plastic Surgery where they look at the symmetry of celebrities faces, and then determine who others see as attractive. So of course there's no question as to why Hazza ended up at the number one spot of having both a perfect chin and eyes. Have you seen how dazzling and green they are?

Incase a reminder is needed as to how mesmerizing they are, why not take a look at his Rolling Stone cover, which he posted on Instagram a few months back. It’s hard to not fall for those smoldering eyes.

So how do scientists determine who should be on the list? Well, they study the distance of the eyes and then divide that number by the eye’s length. A similar calculation goes for determining what exactly makes a perfect chin, all of this is according to math and science. Fans have their own opinions as to what makes the musician and other performers and artists they're fans of attractive.

That wasn’t the only list the "Sign of the Times" singer came up on the top of. Science also says he’s number four when it comes to having the perfect face shape. He was joined by another familiar face on that list – Zayn Malik who came in at number nine.

There’s only one huge problem with this list, why aren’t the other 1D guys on it? Aside from each also having eyes that could melt the heart of anyone, they’ve each got dazzling smiles and faces too! Liam Payne, Louis Tomlinson and Niall Horan also totally deserved an honorable mention.
