The assault took place in Arequipa, Peru, back in January, but footage just started making the rounds this week.
It is unclear what Renzo Zanabria Huanca and Sandra Bruna Morales were discussing, but they quickly ended the conversation as soon as they saw Lupo approaching.
Zanabria quickly fled the scene, leaving his 25-year-old paramour to face off against his jilted spouse.
In the surveillance video, Lupo can be seen grabbing her alleged rival by the hair and throwing her on the ground.
She then proceeds to drag the victim to a nearby ravine and toss her in.
Lupo is heard shouting a few obscenities into the ravine before finally walking away.
Bruna, who fell about twenty feet, managed to escape the altercation with only minor cuts and bruises.
She later denied being the husband's lover, telling a local media outlet that Zanabria had harassed her repeatedly, leading his wife to falsely believe they were having an affair.
