Soap opera star Jessica Serfaty instructed her billionaire ex-fiancé Leonardo Maria Del Vecchio that she was pregnant over the summer time — but wasn’t positive whether he or another man was the father, the Italian-born Ray-Ban inheritor claims.

Del Vecchio, 31, said in an interview with The Post that in August he was lounging on his yacht moored off the Mediterranean island of Sardinia when Serfaty called him from Los Angeles with the pressing information.

The call kicked off a scramble in which Del Vecchio — whose fortune has been estimated at more than $5 billion — said he chartered personal jets to fly Serfaty and a workforce of medical doctors to Sardinia for a collection of paternity checks, including one aboard his yacht, that in the end indicated he wasn’t the father.

Despite no longer being a couple, Del Vecchio said he and Serfaty slept collectively in early July in Monaco while staying at the Hotel de Paris in Monte Carlo.

Immediately afterward, Serfaty — who appeared on “America’s Next Top Model” and starred as lawyer Sloan Petersen in “Days of Our Lives” — flew to Rome, where she slept with another man: a mogul in the liquor enterprise, according to Del Vecchio.

A recording of a telephone call between Del Vecchio and Serfaty reviewed by The Post also captures her acknowledging the encounter.

“I had sex with Jessica on the fourth or the fifth of July. Then she flew to Rome apparently seeing this guy,” Del Vecchio instructed The Post. “Then after a month, she was like, ‘I’m pregnant — It can be you or him.’”

The claims come as Del Vecchio faces allegations that he employed a reputation-management operative to wage a vicious smear marketing campaign against his former fiancée, including by spreading claims on-line that she was a prostitute — accusations detailed in current investigations by The Hollywood Reporter and The New York Times.

Leaked audio recordings revealed by The Hollywood Reporter captured a profanity-laced change in which a fixer working with Del Vecchio said of Serfaty: “wow is it going to get f–ing nasty for this girl.”

Serfaty didn’t reply to The Post’s a number of requests for remark, including texts, emails and a message despatched to her Instagram account.

Serfaty publicly denied being pregnant rumors earlier this month, telling Page Six on Oct. 13: “Not pregnant. Most definitely not with Leo.”

While they waited for the paternity check outcomes, Del Vecchio said he and Serfaty — alongside with her ex-husband, Ididia Serfaty, and their son Roman — flew to his house in Milan, where they took two extra checks.

A few weeks later, in September, Del Vecchio said he phoned Serfaty to ship the outcomes.

“I’m going to tell you what’s going to happen — I’m going to Rome on Tuesday. I’m going to have a back up test to make sure that you’re not lying to me,” Serfaty said, according to the telephone recording reviewed by The Post.

The recorded dialog also captures Serfaty claiming that the man had provided her $5 million to have a child with him, though she said she didn’t intend to settle for the supply.

“I’m having it aborted, but I’m going to have a test done anyways,” Serfaty said, according to the recording. “I don’t want a baby with this guy. I don’t care about the money.”

The present standing of Jessica Serfaty’s reported being pregnant couldn’t be discovered.

Del Vecchio, who denies orchestrating a smear marketing campaign, contends that Serfaty has been the one attacking him publicly because she was upset by the reported paternity outcomes.

Roman Serfaty, 18, instructed The Post that his mom was upset by the reported outcomes because “It was my understanding that she wanted it to be Leo’s.”

“The moment that she discovered that it was not mine, she went to the newspapers again and again,” Del Vecchio said. “I never did any campaign against her. She did everything to have some advertisement, let’s call it. She falsely alleged and reputationally damaged me and betrayed on every possible angle.”

Del Vecchio said the allegations have broken his repute and difficult enterprise dealings involving EssilorLuxottica and Delfin, the funding firm owned by his household.

He said he hopes the paternity-test outcomes will assist clear his identify, although he declined to elaborate on which enterprise dealings have been affected.

Separately, the Del Vecchio household is embroiled in a bitter feud over management of Delfin, which acquired a reported €30 billion takeover supply from Czech billionaire Michal Strnad, according to Reuters.

Del Vecchio is one of eight heirs to the large fortune left by his father, who based eyewear large Luxottica in the Sixties. Its successor, EssilorLuxottica, owns manufacturers including Ray-Ban, Oakley and Persol.

The ugly spat is the newest chapter in a feud between Del Vecchio and Serfaty, whose relationship has been the topic of superstar gossip for years. The pair grew to become engaged in 2023, celebrating their romance with appearances at the Met Gala and other glitzy outings.

But the couple had a falling out in 2024 after Serfaty accused Del Vecchio of abusing her aboard a yacht close to Saint-Tropez. Serfaty said Del Vecchio hit her in the head, while Roman Serfaty, who was current, said his mother broke a vodka bottle over Del Vecchio’s head.

Serfaty rapidly retracted the allegation, but later instructed The Times she did so because of Del Vecchio’s alleged smear marketing campaign.

Meanwhile, Jessica Serfaty — a former girlfriend of actor Ed Westwick, influencer Logan Paul and One Direction singer Niall Horan — faces contemporary authorized woes.

A beforehand unreported courtroom submitting accuses her of giving her son Roman, then 17, what witnesses believed was ketamine at an after-party in Los Angeles on her birthday in April. The submitting also alleges that months later she struck him on the back, leaving a welt.

According to the submitting, Jessica Serfaty gave Roman and two of his associates a small baggie containing what they believed was ketamine after they requested her for medicine. The submitting contains images of the baggie, but the substance has not been independently confirmed as ketamine.

“She gave him drugs on her birthday,” Ididia Serfaty — a Los Angeles-based biotech entrepreneur — instructed The Post. “That’s, I hate to say it, shameful.”

The allegations seem in an October submitting in Los Angeles County Superior Court submitted by Ididia Serfaty and containing statements signed by Roman. The submitting alleges that Jessica violated an present restraining order defending Ididia and Roman from alleged abusive conduct.

“You went back for about three to five minutes and came back with a little bag, which we believed was ketamine,” Roman instructed his mom, according to a transcript of a telephone call included in the submitting.

The submitting also signifies that Roman reported the incident to the Los Angeles Police Department in October. The standing or existence of a police investigation couldn’t be instantly discovered.

Jessica Serfaty denied giving her son medicine, according to the transcript.

“The only time I have ever heard my son ask for drugs was once, and he said it was for a friend, and I never gave him anything,” she said.

Jessica Serfaty was also accused in the submitting of hitting Roman on the back in August, leaving a “large red hand-printed welt.” The incident occurred at Del Vecchio’s house in Milan while the group was awaiting the paternity check outcomes, Ididia Serfaty said.

In a textual content change included in the submitting, Jessica Serfaty appeared to acknowledge slapping her son, claiming he had behaved threateningly toward her.

“The boy deserved a slap after he bowed up to me like he was gonna hit me!!! A pregnant woman!!”

Del Vecchio, who owns a Milan nightclub, made a startling claim about his intercourse life during an October podcast interview.

“I can say that I’ve probably made love with over 2,000 women, and I won over 90% of them by singing ‘Hero,’” he said, apparently referring to the 2001 hit by pop star Enrique Iglesias.
