GG from 'Shahs of Sunset' HIT WITH RESTRAINING ORDER -- Ex-Lover Fears She's A Knife-Wielding Maniac

GG from "Shahs of Sunset" has a cache of deadly knives, and she's willing to use them to slash up her ex-boyfriend ... so says the ex-boyfriend who just got a restraining order against the reality star, TMZ has learned.

GG's ex-boyfriend Sean Sette just filed legal docs begging a judge to protect him from the 5'6", 145-pounder because she's been on a mission to destroy him ever since they broke up earlier this month.

In the docs filed in L.A. County Superior Court and obtained by TMZ, Sette claims GG has been stalking him and "threatening my sexuality." He doesn't really go into specifics about the threats.

Sette also claims GG has been blasting out his personal phone numbers on various social networks while "threatening my family and career."

Sette says what makes him particularly frightened for his life -- "[GG] has an abundance of knives that she carries with her, including illegal knives." Sette says GG has used her knives before, and he believes that she'll use them again on either himself, his parents, and his ex-fiancee.

The judge acknowledged Sette's concerns and has ordered GG to stay at least 100 yards away from him at all times. However, GG can keep her knives ... for now, at least.

The case is due back in court next month.
