He once owned a bakery — but nothing seems sweet about this “sugar daddy.”

One of the men at the center of the murder-for-hire plot that has rocked the NYPD is a bald-headed, tracksuit-wearing accused felon whose Orange County bakery was a hangout for TV tough guys Tony Lip and Vincent Pastore of “The Sopranos.”

Blue-eyed, Bronx-born John DiRubba, 54, last of Howard Beach, Queens, is the much older on-and-off lover of disgraced Officer Valerie Cincinelli, 34, a married mom of two who on Saturday spent her first full day behind bars, in Brooklyn’s Metropolitan Detention Center.

The feds said Friday that she plotted with her boyfriend — who multiple sources have told The Post is DiRubba — to kill Isaiah Carvalho, 32, the estranged husband who had sued to divorce her last year and with whom she has a young son.

Still more shocking was her intended second target, the feds allege: the boyfriend’s 15-year-old daughter. DiRubba has a daughter who is exactly that age, according to records and sources.

“She’s getting in the way,” a source told The Post of Cincinelli’s twisted alleged motive to kill a young girl.

Instead of carrying out the twisted plan, the boyfriend wore a wire for the feds, court papers allege.

“Did you do it yet?” Cincinelli was caught on tape asking the boyfriend, after giving him $7,000 in gold coins to pay a “hit man,” who was actually an FBI agent, according to court papers.

“Run her the f–k over,” she allegedly snarled of the girl.

Neither the girl nor Carvalho was harmed.

Instead, on Friday, the feds clinched their case by allegedly having the boyfriend show Cincinelli a staged photo of her husband, “appearing dead in his car,” court papers said.

Her response? She coolly mused aloud about “what her alibi would be if she were to be questioned by police,” the feds allege.

Chillingly, in March 2018, Cincinelli allegedly threatened DiRubba, telling him: “I hope your daughter dies,” according to documents from a now sealed Queens criminal case, cited by Black Star News.

Cincinelli was accused of calling DiRubba on the phone in violation of an order of protection from Queens Family Court, and was arrested for second degree aggravated harassment and criminal contempt in the first degree, the outlet reported at the time.

“You ruined my life. You’ll see what happens to you,” she allegedly shouted, according to the documents cited. “You better keep your mouth shut. I hope your daughter dies.”

DiRubba has an open felony grand larceny case in Manhattan, and his rap sheet includes a 2008 plea deal from Bergen County, NJ, on a charge of receiving stolen property, records show.

The wire-wearing beau paid Cincinelli’s bills and car payments, sources told The Post.

But even as he dated the still-married Cincinelli, DiRubba had invited a steady stream of lady friends up to his second floor, three-bedroom apartment overlooking Howard Beach’s Shellbank Basin, his former landlord said Saturday.

“He used to tell a lot of people this was his house. When he moved in, he told me he was a movie star. I didn’t believe him,” the landlord said.

Cincinelli’s dad, Lou, insisted Saturday at his daughter’s Oceanside home that DiRubba was the real culprit.

“He just about put the words in her mouth and recorded what he wanted when he wanted,” the angry dad said Saturday.

“I think it will all end up boiling out in the water and coming clean. The guy is a psycho, he’s a nut.”
