A 39-year-old woman named Adriana and her 37-year-old husband, Leandro, both Brazilian, met when Adriana moved back to her hometown in São Paulo. They soon fell in love and moved in together.
Both of them had both been abandoned as babies, and each had tried for years to find their birth mothers.
They knew that their mothers both shared the same name, Maria, but figured that it was just a coincidence.
But Adriana was reunited with her birth mother recently after she went on a radio show that specializes in finding lost relatives.
It was then that Adriana's mother told her that she had a younger brother, who turned out to be Leandro.
While Adriana was initially upset upon hearing the news, she and Leandro have said that they will stay together despite the shocking discovery.
They never legally married, but have a 6-year-old daughter together.
