'Entourage' Hottie -- I Fear My Father Could Murder Me

The chick who played E's psycho ex-girlfriend Ashley on "Entourage" claims she's living in fear of her violent, porn-obsessed parents ... but TMZ has learned, the judge just ain't buyin' her story.

27-year-old Alexis Dziena filed documents in L.A. County Superior Court earlier this month -- asking a judge to slap her parents with restraining orders ... after her mother and her father allegedly roughed her up and threatened her.

According to the docs, Alexis claims her parents are upset because she wants to take away their access to her personal finances. She also claims her father is blowing her money on liquor and porn.

In the docs, Alexis claims, "I fear that [my dad] will do anything to get my money in his hands. I believe murder or violence or manipulation are all possible outcomes."

She asked a judge to keep her folks 100 yards away from her at all times.

But this week, a judge REJECTED her request -- claiming Alexis doesn't have any "reasonable proof" to back up her claims.

Still, Alexis will have a chance to plead her case to the judge in person -- she's scheduled to appear in court for the matter on October 3.
