See Twin Strangers Meet For the First Time

— -- A Swedish teen hit the jackpot this month after searching for her doppelganger on a website that unites look-alikes from across the globe.

Now, the pair have come face-to-face for the first time since discovering their uncanny resemblance.

"I was afraid Shannon and I wouldn't look like each other in person but it turned out I had nothing to worry about...she is definitely my doppelganger," Sara Nordstrom of Orebro, Sweden, said in a Q&A released to ABC News. "It felt a bit surreal when we finally met, a bit like looking at yourself."

Nordstrom, 17, said she came across her twin stranger Shannon Lonergan, 21, on twinstrangers.com, just one month after posting her photo on the page.

When she hadn't heard back from Lonergan, Nordstrom said the team from Twin Strangers posted their match on Facebook and had her fly to Ireland so the pair could meet.

"Trying to describe the moment you meet a stranger who looks almost exactly like you is very hard," Lonergan of Tralee, Country Kerry, Ireland, said. "All I can say is it felt very surreal and almost dreamlike. But once I saw Sara's face I felt my butterflies disappear. A weird sense of happiness took over when I realized I has actually met my doppelganger. I could not stop smiling."

While Lonergan said their personalities are different, their appearance -- from their noses, mouths, lips and eyes -- are eerily similar.

Both Lonergan and Nordstrom said they plan on staying in touch through social media.
