It sounds like a Hollywood film script: twins separated at birth grow up in different continents and find each other online.
But no, this is the real life tale of Anais Bordier, a French fashion student living in London and Samantha Futerman, a hopeful actress from the US.
The two girls, who found each other via a YouTube video, have since discovered that they were both adopted and were both born on the same day in Seoul, South Korea.
The girls first met on Skype - a freaky experience for them both that lasted three hours - and have subsequently met in real life, had a DNA test to see if they're twins and filmed a documentary about it all: they say you have to watch the film, 'Twinsters', to find out if they really are twinsies.
