Twin girls who became famous because of their unique eye color are all grown up now

Every year different sets of twins are born in the world but one fan dubbed these two "The world's cutest twins," and it easy to see why.

These two lovely girls stole the heart of millions of followers on the Internet. Their eyes captivate anyone who sees them and the pair can't stop getting media attention.

They were born in 2013, and now that they're growing up, they're becoming one of the most important Instagram phenomena to date. Although Megan and Morgan Boyd are all-around adorable, there's one physical feature that really stands out, their bright blue eyes.

These twins from Philadelphia became a sensation after their mother's pictures of them quickly went viral, and after that, her account amassed over 122k followers.

While Megan has two blue eyes, Morgan has one blue eye and one that's dark brown, a condition called Heterochromia. While heterochromia is not that uncommon, finding African Americans with blue eyes is a rare combination. According to Stephanie Boyd, the girls' mom, the blue eyes run in her family.

She has the exact same color as her girls, her grandfather had it too, and there are two other members of the family that actually have heterochromia like Morgan.

It's easy to see why they say they're the most beautiful as everyone could agree that this pair offers a unique appeal that sets them apart from other children.

According to In Style, their mother admitted that both Morgan and Megan are "aspiring models," as it is obvious that they're accustomed to posing for the camera.

Their mother also explained that both girls are also involved in deciding the outfits they're going wear in their photoshoots.

"They said that they love this outfit because the shirts match their eyes. They love fashion and they like to dress the same," their mother told Monagiza. And although they could grow up to be top models, right now they're just two normal children who are enjoying a little bit of fame on Instagram.

Her mother is convinced that the girls have a future in the fashion industry, not only because of their gorgeous and unique factions but also because they clearly have an eye for clothes and are already developing their own fashion style.
