IT'S TV MATCH MADE IN HELL

Love at first sight is wonderful, but getting “Married at First Sight”? Not so much.

A Queens woman who went on the FYInetwork reality show in which strangers get hitched moments after meeting has filed court papers saying her TV groom threatened to kill her and her family.

Jessica Castro, 30, claims her experiment in whirlwind weddings on “Married at First Sight” went horribly wrong when her groom, Ryan De Nino, of Staten Island, made a chilling vow in March.

“I will break you into fking pieces,” the 29yearold business consultant said, according to a Queens Family Court petition filed Friday.

“I will break your dad into pieces. I will make your whole family disappear — and your fking dog-ass sister’s boyfriend.”

And while taping a reunion show in May, De Nino allegedly made a slipup reminiscent of millionaire murder suspect Robert Durst’s admission that he “killed them all” on the HBO documentary series “The Jinx.”

According to the petition, De Nino was caught on a live microphone saying, “She’s fking dead. When I get back to Brooklyn, she’s fking dead, this girl.”

Castro, a lawfirm receptionist, and De Nino appeared on Season 2 of the show, which also airs on the A& E network. After getting married in December, they lived together for several weeks, during which the producers taped the conflicts that would naturally arise from two strangers coupling.

The couple ( pictured) broke up shortly after Castro caught De Nino cheating on her on Valentine’s Day, sources say.

The show’s producers took De Nino’s death threat on the May show seriously and provided Castro with security personnel, according to the filing.

De Nino is facing Family Court charges of harassment, menacing and stalking. Court referee Julie Stanton ordered De Nino to stay away from his wife until their hearing on July 13.

De Nino did not return calls for comment, but a post on his Instagram account said he was “disgusted” by the allegations.

Castro’s lawyer, celebrity divorce attorney Marc Rapaport, declined to comment on the order of protection but said his client is “considering all her legal options including potential claims against A& E.”

Rapaport is subpoenaing A& E because he suspects the show’s executives knew about De Nino’s volatile nature yet cast him anyway to add sensationalism to the series.

A spokesman for the show’s producer, Kinetic Content, said: “We don’t know all the details and can’t comment on the specifics.

“What we can say is that, unfortunately, couples on the show can go through real divorces, and divorce can often be difficult.”
