Now here's a twisted family tree.

A Brazilian woman in search of her birth mother got the shock of her life when she discovered her husband of seven years was actually the brother she never knew she had.

Adriana and her husband, Leandro, both knew they had been abandoned by their birth mothers at a young age.

But they didn't know it was by the same woman.

Adriana located her birth mother recently through the help of a radio program. On air, the woman disclosed that she'd also had a son whom she had abandoned named Leandro.

Despite their apparent family ties, the two plan to stay together.

"Only death is going to separate us," Adriana told Radio Globo. "All this happened because God wanted it to happen."
