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."

After five years of marriage, Sandra Bullock filed for divorce from Jesse James in April 2010 in the wake of his reported 11-month affair with tattoo model Michelle "Bombshell" McGee. After their split, the "Monster Garage" host began dating tattoo artist and reality star Kat Von D. The two shared a year-long on-again-off-again romance (and brief engagement) that ended after Von D discovered that James had allegedly cheated on her with 19 women.
Eddie Cibrian cheated on wife Brandi Glanville with waitress Scheana Marie while Glanville was pregnant with the couple's second child back in 2006. Several years later, Cibrian was back to his philandering ways when he infamously got hot and heavy with LeAnn Rimes on the set of the Lifetime movie "Northern Lights." Glanville and Cibrian called it quits in August 2009, shortly after he and the singer went public with their previously rumored relationship. But that's not all. In January 2013, Marie told Radar Online that after Cibrian and Rimes began dating, the "CSI: Miami" actor made attempts to rekindle their relationship by inviting her out for drinks.
Couple of two years Usher and Rozanda "Chilli" Thomas -- a member of the R&B trio TLC -- broke up in 2004 after she learned that he had been unfaithful.

In September 2012, Foster told "Entertainment Tonight" that the singer had cheated on her with two of her bridesmaids. That one had to "Burn"...
Reese Witherspoon filed for divorce from husband of seven years Ryan Phillippe in November 2006. After the split, Us Weekly reported that Phillippe's alleged fling with "Stop Loss" co-star Abbie Cornish may have factored into the divorce. Cornish and Phillipe's three-year romance came to an end in February 2010 following what People magazine called "months of tabloid speculation that Phillippe [had] been unfaithful to Cornish - regularly hitting the nightclubs and being linked to other women."
Elizabeth Taylor was married eight times to seven men (she married and divorced Richard Burton twice) before she died in 2011. According to The Sun, La Liz was rumored to have cheated on her second husband, Michael Wilding, with producer Michael Todd -- the man who would eventually become her third husband (pictured right). While she was married to fourth husband Eddie Fisher, Taylor reportedly began having an affair with Burton, who was also married at the time. The pair left their respective spouses and tied the knot in 1964 before splitting in 1974. They remarried in 1975, and divorced again less than a year later in 1976.
