Well, apparently Erica Mena from Love And Hip Hop is a real life fighter. Not only on the show, but everywhere. The video below shows Erica Mena getting into a fist fight earlier this year with the father of her child. The father if her child appears to be Raul Conde from Terror Squad.
Something you may find interesting, Erica also calls for her phone at the end of this fight. Which makes me really think the show is staged, maybe even the fight being staged of her previous fight.
