A secret affair of a mother from Xiamen, China was exposed after the DNA tests revealed that one of her twins had a different father.

According to reports, the partner of the woman wondered for a long time why his twins did not look a lot like each other, and why one of them had different nose, eyes, and mouth.

Basically, the other twin did not resemble with him in any freaking way!

But, the father never considered the fact that one of the babies could have a different father, because it sounds impossible.

The tests were done by the Fujian Zhengtai Judicial Authentication Center in Zemen, which is located in East China’s Fujian Province.

The mother even accused her husband of tampering with the DNA results. Eventually, the mother admitted that she did have a one-night-stand with a man.

The news of the rare case was made public by Zhang, the director of the Fujian Zhengtai Judicial Authentication Center, she said, the rare case of super-fecundation is when 2 eggs are fertilized during the same cycle by 2 fathers.

Zhang added, “This is a very special case. It means that the woman had sexual relations with two men – and was impregnated by them at the same time.”

“They’re fraternal twins. A very uncommon and rare case.”

Zhang said that the couple has “sorted the matter out themselves”.

The partner of the mum said, “I obviously still want my own child, but I’m unwilling to raise someone else’s child.”
