A mother-in-law who demanded a DNA test accidentally exposed her own secret after she accused her daughter-in-law of cheating.
Talking about her granddaughter's 'unusual' appearance, she accused her daughter-in-law of having an affair due to their newborn having green eyes - a characteristic nobody else in their shared family has.
Making multiple remarks about the accusation, the new mum ended up putting her husband and baby through DNA testing to clear her name.

But when doing so, she accidentally uncovered her mother-in-law's 29-year-old secret, reports the Mirror.
The new mum explained the story on Reddit saying: "I gave birth to my daughter two months ago and despite my husband telling me he knows I'd never cheat on him, I wanted to give our daughter a paternity test.
"The reason - she has green eyes. My husband and I don't have green eyes, my parents don't either and neither do my in-laws - no one in my family has them.
"My husband said it was probably some weird genetic thing but I wanted the test for his peace of mind.
"He kept refusing because he trusts me but his mother keeps commenting on her eyes, as do the rest of his family, who keep making comments about me possibly cheating.
"Even my family find it odd our daughter has green eyes."
Much to her delight, her husband eventually agreed to do the paternity test and as expected, the results came back saying he was the father of their daughter. But after reading the results in more detail, she realised something was very wrong.
"Our daughter is his but my father-in-law isn't my husband's father" she added.
"My in-laws have been married for decades so the idea that my mother-in-law cheated on my father-in-law never crossed either of our minds.
"My husband wants to confront his mother but I'm telling him to wait. Yes, she's a liar and a hypocrite but we need to think this through.
"I agree my father-in-law should know but we're both tired from taking care of a newborn, we've found out something shocking and were not thinking rationally.
"He wants to tell his father and so do I but the fall out will be apocalyptic.
"I just wanted to give him peace of mind and instead I started the end of his parents marriage and possibly blew up his family."
Commenting on her post, one user said: "Your mother-in-law was projecting so much now her a*** is uncovered."
Another user added: "What gets me is the fact that she pushed for you and her son to do the one thing that would expose her secret.
"All she had to do was keep quiet and no one would’ve been the wiser."
A third user said: "Next time your mother-in-law talks about green eyes, just look her dead in the eyes and say 'Oh, I know how they got green eyes... there are ways of finding these things out'."
