A couple discovered they are actually brother and sister on a live radio show after they both spent years trying to track down their birth mother.
Adriana and partner Leandro, who have opted to withhold their surname, discovered their respective backgrounds after seven years together. They also have a six-year-old daughter.
The Brazilian couple successfully located their birth mothers, both named Maria, as they were each abandoned as babies. It was only this week that they realised they were looking for the same woman.
While Leandro stayed in the town where he was born, near Sao Paulo, Adriana moved away, was married for 15 years and had three children.
However, her marriage broke down 10 years ago and she moved back home, where she met Leandro.
Still desperate to locate her birth mother, Adriana contacted local radio station Radio Globo to see if they could help and, after researchers traced her mum, the two were reunited live on air last week.
