Mary Kate and Ashley Olsen are one of the most famous sets of twins in the world. Anyone born between 1980-2000 should definitely know who these two are.
But we were shocked to find out THEY AREN’T IDENTICAL TWINS!
It turns out that they are actually non-identical twins - better known as fraternal twins! It is surprising because they look so similar.
Fraternal twins are actually conceived from two separate eggs in the womb, making it very unlikely the two kids will go on to share the same features, but Mary-Kate and Ashley did!
This is news to us, but we're sure there are some dedicated fans that knew this due to the fact that Mary-Kate is around an inch shorter than Ashley.
