Here's a lesson in what not to do when confronting your husband's mistress.
The Inquisitr reports that one Peruvian woman became so enraged after discovering her husband talking with his alleged mistress that she pushed the mistress off a cliff as her husband fled the scene.
The entire altercation was captured on a security camera and can be viewed in the Spanish-language news clip above.
After suffering a 20-foot fall, the mistress was reportedly treated at a hospital for minor lesions and bruises but was not seriously injured.
But is the video real? Only time will tell -- like in the case of this viral video of a scorned Brazilian woman bashing her husband's car, which turned out to be a publicity stunt for the TV show "Revenge."
