Video inside

A huge brawl erupted during the taping of the "Love and

 Hip Hop: Atlanta"reunion show in NYC Tuesday night

 … leaving several cast members -- and their weaves -- 

injured. Multiple sources on the set tell us the fight

 involved Benzino, his fiancee Althea, Stevie J, Joseline, 

Debra, Tammy, and Mimi -- and the whole mess started

 when Benzino cracked a joke about Stevie J and Joseline 

doing drugs.

We're told Stevie jumped up to get in Benzino's grill, but 

security guards stopped him. That's when according

witnesses  Stevie's girl Joseline sneak attacked Althea.

 After that, all hell broke loose -- weaves were torn out in 

the chaos  and every time security broke up one fight … a 

different one would spark up between other cast members.

We're told most of the fighting was between the women --

 although at least one male security guard took a shot to the 

face … from one of the chicks. From what we can tell the 

only smart decision all night was someone calling 911.

 Cops and paramedics responded -- at least three people 

got treatment.

We know what you're wondering, and the answer is -- 

YES … we're told VH1 cameras were rolling during most 

of the violence. The Seeds of ratchetness appear to have 

been sown Monday night ... when a nude pic of Benzino 

and Althea was posted on Stevie J's Twitter page.
