Ryan Seacrest Vs Reality Star

The show is being hailed as the "Persian Jersey Shore" -- featuring a bunch of young, rich Persians galavanting around Los Angeles.

But according to a new lawsuit, filed by a woman named Kathy Salem, the show is just as insane and violent as every other reality show in TV ... a lesson she claims she learned at a fancy Hollywood party back in July.

Salem claims she signed a waiver before entering the shindig and understood she would appear on the show ... but "she did not understand that she might be blind sided and forced against her will to play a demeaning and humiliating role."

Salem claims when she was inside the party, she was confronted by the stars of the show -- who began to bully her and become "verbally abusive" because she was talking to a man who was allegedly engaged.

Salem claims things escalated quickly -- and she was attacked by multiple people -- one of whom tried to rip her top off and another who threw a cup of water in her face.

Salem claims the show is set to air in February -- but she wants a judge to force Ryan to pull any footage in which she appears.

Salem is suing Seacrest, his production company and Bravo -- demanding at least $100,000 in damages.
