She married her brother and did not know it for 7 years
The Brazilian couple's life seemed complete: Husband and wife for seven years, with a daughter.
But when she went in search for her long-lost mother, she stumbled on a bombshell - she had married her own brother.
Sao Paulo couple Adriana, 39, and her husband Leandro, 37, were both abandoned when they were still babies. They only knew their mothers shared the same name, Maria.
But neither ever imagined - until this week - that the women they had both been searching for could have been the same person.
Many people were called Maria
Adriana, a cosmetics saleswoman, hadn't seen her mother since she was just one, the Mail Online reported.
Her mother left home, so she was raised by her father. She moved away to work as a housemaid, was married for 15 years and had three children.
But that union broke down.
She moved back to her home town in southeast Brazil, where she met Leandro 10 years ago, fell in love and moved in together.
Meanwhile, truck driver Leandro found out aged eight that his own mother had also abandoned him.
The woman he knew as his mum was actually his stepmother.
Determined to search for her mother, Adriana decided last month to contact a radio station in their town to ask for help.
This week, the two were reunited live on air, on Radio Globo's The Time Is Now programme, which specialises in finding lost relatives.
"I don't believe this"
But it was a bittersweet discovery.
At the end of the interview, the mother revealed she also had a son who didn't know her, Leandro.
As it becomes clear that it is the same Leandro that she was married to, Adriana was heard weeping uncontrollably: "I don't believe that you're telling me this.
"Leandro is my husband," she sobbed.
At the end of the interview she said: "Now I'm scared to go home and find out that Leandro doesn't want me any more. I love him so much."
Together till death
Adriana and Leandro - who never married legally - told Radio Globo on Tuesday that they would stay together, despite the shocking truth that they are actually brother and sister.
Here's what Adriana said:
"Only death is going to separate us.
"All this happened because God wanted it to happen.
"Of course it would have been different if we had known all this before, but we didn't and we fell in love.
"We thought it was funny that both our mothers had the same name, but it is a common name so we just thought it was a coincidence.
"At first we were really knocked by it all.
"But we had a family meeting and told everyone that we are going to stay husband and wife, whatever anyone might think.
"We have so many plans together, nothing's going to break us up, nothing."
The couple said they don't blame their mother for leaving them, have spoken with her a number of times since and plan to meet up soon.
