Long lost twins who were separated at birth and grew up 5000 miles away have finally been reunited, thanks to a YouTube video and social media.

Last year, Anais Bordier spotted Samantha Futerman in several YouTube videos. Noticing they were almost identical, she sent a Facebook message asking where she was born.

Bordier wrote: "About two months ago, my friend was watching one of your videos with Kevjumba on YouTube, and he saw you and thought that we looked very similar..."

She added: "I checked more of your videos (which are hilarious) and then came upon the 'how it feels to be adopted'... and discovered you were adopted too.

"You can check my Facebook if you want to check the pictures and videos. It's more obvious on the videos... Let me know... Don't freak out."

A few messages later, it was revealed they were both born in Busan, South Korean, on November 19th 1987. Believing they were related, the pair began to exchange messages online. Bordier grew up in France, but lived in London, whereas Futerman grew up in New Jersey in the US. Neither knew each other existed.

Although they spoke different languages and grew up on different continents, the twins reunited over social media.

In Samantha's YouTube clip How It Feels To Be Adopted, she says: "I don't think about it all the time, I'm not like little orphan Annie," Futerman said in the clip.

"I was born in Korea and four months later I arrived at JFK airport, where apparently all babies don't come from ... and I met my family for the first time."

In the videos, Anais noticed they shared not only their appearance, but they also had the same laugh and mannerisms.

Three months later, the pair met in London and again in Los Angeles and New York. Although they were convinced they were blood relatives, they still wanted confirmed. Finally, a DNA test revealed Samantha and Anais were twins.

Months later, the sisters are making a documentary about their incredible discovery. They are raising funds through the Kickstarter site and have reached over $73,000 out of their $80,000 goal.
