Word on the street is that during "Love & Hip Hop: Atlanta" Karlie Redd's 'Redd Champagne" hair launch in Atlanta last night, rapper Lil Scrappy's fiance Erica Dixon and his ex-girlfriend Shay Johnson got into a physical altercation that left both chicks injured!

According to FunkyDineva, during the event, the duo got into an argument outside of a nail salon's parking lot, that left Shay bloodied and scratched up.

Here's what happened..... Erica, who was already at the party when Shay arrived, allegedly began exchanging words with Shay before she could make it inside the venue. Sources from Erica's camp claims, Shay was the instigator and should be blamed for the starting the fight.

According to eye witnesses, Shay's hair was all messed up and was indeed bleeding when it was all over. One source went on to say that after the fight, Shay was taken to a bathroom where she remained for about an hour while one of the stylist at the salon attempted to put her hair and face back together.

Here's what Erica had to say about the incident:

"WTH? I don't need any type of weapon, I got these hands!! #runupgetdoneup #pointblankperiod."

Shay then responded with:

"LETS SET THE RECORD STRAIGHT!! This is what im looking like 4/11/13! Apparently them PAWS need 2 go back in training!"

Shay then shared the pic below...amidst the rumors about her getting beat up by Erica:
