'Love and Hip Hop: Atlanta' Star Joseline Hernandez Swears ... My Show is Fake!

Joseline Hernandez from "Love & Hip Hop: Atlanta" knows what's real ... and it's not her show.

Hernandez testified under oath in a videotaped deposition that she and other cast members stick to a script.

She's being sued by former co-star Althea Eaton, who claims Joseline got high on crack cocaine and then beat the crap out of her during a reunion show.

During the depo, Althea's lawyer wanted to know if the real Joseline emerged during the fight in question, or whether it was pre-programmed.
