Season 7 "American Idol" contestant Asia'h Epperson claims her ex-boyfriend beat the crap out of her on multiple occasions ... and then threatened her with death ... this according to court docs.
Epperson -- who placed in the Top 16 on "A.I." in 2008 -- filed a request for a restraining order against her 27-year-old ex BF ... claiming the guy has a history of "choking me and slamming me on the ground, fighting and wrestling me."
According to the docs filed in L.A. County Superior Court, Epperson claims the abuse got so bad, the ex began making "threats about killing me and then himself."
She claims he also, "called people out of my phone and threatened them as well ... threatened to shoot my friends."
Fortunately for Asia'h ... her request was granted and the ex-BF was ordered to stay 100 yards away from her at all times.
Both sides are due back in court on June 10.
