The NYPD cop accused of plotting to murder her estranged hubby — as well as her boyfriend’s teen daughter — was denied bail because of her “lack of impulse control” and her “defensiveness.”

A federal judge ordered Valerie Cincinelli, 35, to remain behind bars at the Metropolitan Detention Center in Brooklyn until her trial, according to court documents filed Friday.

The Oceanside mom was arrested in May on charges that she hatched a plan with her boyfriend John DiRubba to arrange hits on both her husband, Isaiah Carvalho, and DiRubba’s 15-year-old daughter.

She has pleaded not guilty to two counts of murder for hire and one count of obstruction of justice.

Central Islip Judge Sandra Feuerstein noted in her ruling that Cincinelli “poses a danger to the safety” of the victims, pointing to her “lack of impulse control and remorse” as well as her “defensiveness” when defying court orders.

Cincinelli allegedly attempted to destroy two iPhones around the time of her arrest, then got into hot water behind bars for ignoring court rules by placing calls from jail.

“The court finds by clear and convincing evidence that defendant poses a danger to the safety of the allegedly intended victims and the community, particularly in light of the serious risk that defendant would attempt to obstruct justice, as evidenced by her alleged conduct in destroying and/or attempting to destroy evidence prior to her arrest and her disobedience of court directives while in custody,” the judge wrote.
