An angry pregnant wife has attacked her cheating husband’s mistress by allegedly forcing red-hot chili peppers into her vagina.

Vietnamese media reports Ly Chanel, 23, had noticed her husband had begun disappearing for hours on end.

They’d only been married seven months. And she was already bearing his first child.

Earlier this week, she followed Chien Keo, 24, to what turned out to be a motel rendezvous in the Thai Nguyen province in Vietnam.

Three-months pregnant Ly interrupted the pair and stuffed chilies into the mistress’s vagina while her three female friends held her down on a motel bed.

The pictures of the incident have shocked internet readers across Asia.

And their malevolent message backfired.

Furious followers wanted to know why she punished the mistress so severely but ignored her wayward husband. They accused Ly of being cruel.

Ly responded before shutting down her Facebook page:

“How can he care for us if he cheats with another girl? A woman who destroys the family? Women can forgive easily but they can never forget. Jealousy is painful. She will know this.”

“There are people who hate me now, but life is like that, you cannot please everyone.”
