An Italian businessman thought his young model wife had met a cruel fate when she mysteriously disappeared in July after telling him she was going outside for some fresh air — but what he found out was even more of a shock.

Gianluca Cervara was initially so worried that he reached out to authorities, fearing his new bride, former Miss Ukraine Anna Zaiachkivska, had been kidnapped — or worse, according to published reports.

But the search quickly came to a halt when Cervara discovered Instagram photos of his beloved, who clearly wasn’t in danger — she was living it up in New York with another man.

“Your Husband in Milan And Parents say thank You for Be in New York with address Of another Man,” the devastated billionaire sarcastically wrote alongside social media photos the 24-year-old posted after leaving Italy.

“Wooooow Married escape without Tell And with fake address in NewYork!!” he wrote in response to another photo.

The pair wed on Dec. 22, 2015, in an Italian registry office, and had planned to hold a formal church ceremony in September.

But now Cervara is out for revenge, suing Zaiachkivska for breaking their prenuptial agreement — and his heart. He even claims that before she made her escape from Milan, she took $7,000 and a cellphone from his home safe.

Zaiachkivska, who was crowned Miss Ukraine in 2013, told a Ukrainian website that she’d left him because he’d become abusive.

“He raised his hands against me,” she told tochka.net, according to the Daily Mail.

“The first time when he did it I ran away to my parents’ house in the western Ukrainian city of Ivano-Frankivsk. I did not tell them what the matter was.

“He came to get me, and I gave him a second chance, but during an argument he spat in my face, and I simply could not take it.”

The last straw was apparently his inattentiveness.

“I had headaches for a week but Gianluca did not care about it,” she griped. “Finally I decided I needed to make changes as I was fed up of living in a golden cage and I ran away.”

Despite her claims of abuse, the Ukrainian stunner had only nice things to say about her hubby when, just a few days before she vanished, she wrote on his Facebook page: “My amazing Gianluca Cervara, thank you that I can be your flower and part of the family.”

Her Instagram page is now littered with photos of her time in NYC. Several photos include the hashtag “freedom.” Cervara, however, is furious that her “freedom” came without so much as an arrivederci.

“Judging by her photos she is in New York and is working as a model there,” he told tochka.net.

“She has lots of pretty photos taken in five-star hotels, she is posing with other men. She does not look unhappy at all.”

“All I can say is she is not the person she is pretending to be,” he added.
