Niamh Geaney and her doppelganger Irene Adams "couldn't believe" the results of the tests.
Identical strangers take DNA test to find out if they're related
These two twin strangers from Ireland who have never met each other before, recently took a DNA test to find out if they were related.
Geaney from Dublin, Ireland told ABC News today she first connected with Adams also from Sligo, Ireland last year November after a friend of Adams' told her she looked like "that doppelganger girl on the news."
"We got in touch, met up and it was absolutely surreal to see yet another one of my doppelgangers in the flesh," said Geaney, 27.
She explained that Adams, 28, is actually the third doppelganger she's discovered so far since creating Twin Strangers, a website and tool that uses facial recognition software to match you to a potential lookalike.
"We clicked instantly, and just like my second doppelganger, she not only looked exactly like but also acted like me," Geaney said.
"It was like watching myself. Our facial expressions are exactly the same, our eyes and nose crinkle the same way, we smile the same and she also talks with her hands just like me."
After the two went to national DNA testing center DNA Ireland, where they gave samples of their saliva, they discovered they were not related after all.
"We were shocked," Geaney said.
"We thought, 'OK, we definitely have to have relatives from the same place somewhere down the line,' but that wasn't the case."
