Filming of "Love and Hip Hop Atlanta" turned into a CRAZY free-for-all Wednesday ... as a massive brawl erupted during production leaving stars bloodied and injured ... and TMZ has the wild cell phone video.
The cast was shooting the opening of a restaurant. Sources close to the show tell us ... the trouble began when Joseline Hernandez walked in with a girlfriend. We're told the friend instigated an argument ... and pretty soon fists were flying.
Karlie Redd was knocked out ... several others suffered bloody cuts ... and somebody threw a bottle at Momma Dee, hitting her in the face.
VH1 cameras were rolling the entire time. Of course they were.
