INSIDE EDITION talks to couples who have so much in common, they actually look like each other!
At first glance, Sam Nagourney and Katharine Walker look like brother and sister. They both have blond hair and bright blue eyes. They have the same shape face and the exact same smile.
But it's not what you think. They aren't siblings. They're boyfriend and girlfriend who just happen to look like each other!
Nagourney and Walker were instantly attracted to each other when they met while working at a Manhattan publicity firm.
"It was love at first sight," said Nagourney.
"I've always been told I have a nice smile. I'm sure he's been told the same, so I'm immediately attracted to his smile," said Walker.
It wasn't just the matching smiles. Looking at them side by side, they both have similar shaped lips and pronounced foreheads.
"I think she's gorgeous. So, if I'm getting compared to her, then that's a compliment and I love it," said Nagourney.
Another look-a-like couple, Natalie Suarez and A.J. Cahill have been in love for three and a half years.
"Everybody finds themselves to be attractive, so I think if they recognize or see some sort of similarity in somebody else, something will click," said Cahill.
Christina Bloom actually created a dating website called findyourfacemate.com that promises to match up couples based on facial compatibility.
Bloom told INSIDE EDITION, "Natalie and A.J. have long faces. They have strong chins and their eyes are spread apart on their face the same way. They're a perfect match."
But if you're thinking it's a little strange to date someone who looks just like you, these couples say they wouldn't have it any other way.
