Lucy and Maria Aylmer are non-identical twin sisters, but most people don't even believe they are related.

The twin girls have gone viral because one is black and the other is white. The girls often get mistaken for just being friends but they have been related since 1997, born to a white father and a half-Jamaican mother.

Even their mother, Donna, did a double-take the moment she saw her daughters for the very first time.

It was such a shock for her because obviously things like skin color don’t show up on scans before birth. So she had no idea that we were so different. When the midwife handed us both to her, she was just speechless.

One thing that is consistent between the two is they are just as different as they look when it comes to their personality too.

A red head with fair complexion, Lucy studies art and design at Gloucester College. Maria, who has caramel skin and brown hair, is a student at Cheltenham College studying law and psychology.

One of the perks of looking so different for the girls is that people don't mistake them for one another, like most other twins.

Lucy says one of the great things about having a twin who looks completely different is that people don’t mistake them for one another.

Most twins look like two peas in a pod — but Maria and I couldn’t look more different if we tried. We don’t even look like we have the same parents, let alone having been born at the same time.

The odds of something like this happening seems like be it would be one in a million, but according to research from 2011, it's more like 1 in 500.

Even though the girls are very different, their bond is unbreakable.
