This scorned beef started over a world famous Midtown deli — but it’ll end in a Manhattan courtroom.
The married owner of the Carnegie Delicatessen was serving a side of sex to a tenant living above the world famous eatery, allegedly carrying on with the woman since 1998, according to a shocking new lawsuit filed by his wife.
Marian Levine, whose family founded the over-stuffed sandwich mecca, claims hubby Sandy Levine was having the extramarital affair with a rent-controlled resident of their building on Seventh Ave. off 55th St.
The two “were engaged in an intimate, romantic relationship, a fact unknown to” Marian, according to the Manhattan Supreme Court suit filed Thursday.
The 10-unit apartment building is anchored by the famous deli that’s served up its gargantuan sandwiches to New Yorkers, tourists and stars since 1937, from Henny Youngman to Jack Nicholson to Taylor Swift — and even President Obama.
Marian, 63, daughter of the deli’s late founder Milton Parker, claims her 71-year-old husband was carrying on with a 66-year-old woman named Penkae Siricharoen for the last 15 years.
Meanwhile Sandy was jokingly referring to himself as the MBD or “married boss’ daughter.”
Marian learned of their alleged tryst in 2011, after Sandy signed an agreement with Siricharoen giving her preferential rent for the next 15 years, the suit claims.
A deli employee told The Post the affair was an open secret.
“This isn’t about money,” he said. “This is a personal issue between her and her husband. She doesn’t need the money.”
Marian, who says she owns the building and only employs her husband as a manager of the deli, claims the sweetheart deal gives the tenant an “artificially depressed” rent of $975 per month when market rate would be as high as $3,000.
“Sandy Levine acted without authority and fraudulently omitted to disclose the true nature of his relationship with Siricharoen,” the miffed Mrs. says in the suit.
Her straying spouse “clearly did not demonstrate sound business judgment or further [Marian’s] business interests.”
She is suing both her husband and Siricharoen. Marian wants the court to evict the woman, who also has a home in Queens, in addition to back rent, the suit says.
Reached by phone, Marian Levine declined to say whether she was separated from Sandy.
Her husband, who spends part of the year in Boca Raton, Fla., according to the suit, could not immediately be reached for comment. Siricharoen did not answer the door at either of her New York addresses.
The couple was the subject of a short-lived reality TV show called “Family Pickle” in 2011, which ended around the time that the wife discovered her husband’s philandering.
The landmark restaurant is known for its stacked sandwiches, typically packed with a pound of meat and all the fixings, with different combinations named after celebs like Woody Allen and Knicks forward Carmelo Anthony.
And the midtown building was notorious even before Marian filed her suit exposing the affair.
The apartments above the deli were the site of a drug-heist-turned-massacre in 2001. The bloodshed, that left three people dead and two seriously injured, happened just one floor above Siricharoen’s fourth-floor unit.
But instead of hurting the deli’s bottom line, the execution-style murders drove more foot traffic into the deli, Sandy boasted at the time.
