An absolutely insane fight went down between friends of "The Real Housewives of Potomac" cast members ... with fists flying and women getting yanked down by their hair in this crazy video.
This exclusive video, obtained by TMZ, shows the cast breaking up a fight between friend of the show Keiana Stewart and another woman, Deborah Williams while at Zebbie's Garden in D.C. Thursday night for Ashley Darby's fashion line launch.
According to the police report obtained by TMZ, Candiace Dillard Bassett told police someone threw a drink at her ... and Keiana says she was hit in the forehead with a glass before getting pulled down in the physical altercation.
You can see Candiace and Ashley clearly in the video, trying to break up the messy brawl ... which apparently resulted in some spilled blood. We're told cops responded, but no no arrests were made. However, police are still investigating.
Sources connected to the show tell us production had already wrapped when the fight went down, so the crew's cameras didn't capture the fight. As Julia Roberts would say ... big mistake, huge.
