Cheating American mum has twins from different dads!

London, May 18 (ANI): An American mother was left dumbstruck after she found out that she had incredibly conceived her twin sons from two different fathers.

Mia of Dallas, Texas, gave birth to babies Justin and Jordan, now 11-months-old, just seven minutes apart and undertook a paternity test after finding the two looking very unalike.

The 20-year-old faced a jaw dropping moment after tests showed that there was a 99.999 per cent chance that the boys did not have the same father.

Mia confessed to having cheated on partner James Harrison with another lover at the time she conceived.

Stunned medics told the young mother different eggs were fertilised by each man within a very short time of each other - a million-to-one condition, which made the twins, in reality, half-brothers.

"When they opened the envelope and told me my jaw just dropped open," the Sun quoted Mia as saying.

"It was the weirdest thing to think two little babies could have grown in my stomach together and been born seven minutes apart but yet have different fathers. I would have thought it was impossible," she added.

Mia further revealed that her partner James had decided to raise both the kids as his own despite her affair.

She added: "I'm lucky because James genuinely loves both the twins. When they get older we will tell them the truth."

Mia is about to become a mum again, but this time she has assured that there was "no question" that James was the father. (ANI)
