Millionaire duped ex-mistress into signing her legal rights away: suit

She should have read the fine print.

The ex-mistress of a top insurance executive says the multimillionaire duped her into signin𓃲g away her legal rights.

So now she’s suing he💝r former paramour, Robert Rosenkranz, claiming the Apri🐷l 2014 pact was a sham.

Miffed mistress Katherine Nelson says Rosenkranz, head of the $10 billion insurance holding com▨pany Delphi Financial Group, rushed her to sign the one-page agreement claiming it was merely to appease his e🐻stranged wife.

Nelson asked Rosenkranz, whom she’d been da♒ting for four years, “if she could show it to a lawyer,” she recounts in court papers.

The Yale grad, who sits on the board of the prestigious Manhattan Institute, told her “not to worry because it was only a ruse [he] created to postpone his divorce; and…it would not affect their relationship,” according to the civil suit.

Nelson admits that she diꦆdn’t read the deal before signing it.

The “silence agreement” prevented Nelson from contacting Rosenkranz or his family, divulging informati꧟on about their illicit affair or bringing any legal claims against him in exchange for $100,000, according to a copy of the deal attached as an exhibit in court papers.

Later, on Nelson’s birthday, Rosenkranz slipped his mistress a card that included a check and a note referencing their “mo𝄹ney-for-sex and silence agreement,” the s༒uit says.

After the two signed off on the statement Nelson “continued to enjoy an intimate loving relationship” with Rosenkranz—kissing him “passionately” in Central Park, jetting ♕off for a romantic getaway in Aspen, and having “intimate relat𓂃ions” at the banker’s Madison Avenue office, the suit says.

Then, two months after the Aspen trip Nelson caught Ronsenkranz canoodling with a coworker 💯at the BLT Steakhouse, according to the Manhattan Supreme Court case.

In court papers Nelson says she conf🌸ronted 𒀰the married man “while tears ran down her face.”

Rosenkranz then got an order of protection against his ex-lover days later, after he “angrily accused her of trying to hurt his family” and even “reached for꧟ her throat,” the suit 🎶says.

Nelson is suing for unspecified damages.

Rosenkranz, who o𓃲wns homes in Aspen, Manhattan and East Hampton, did not return calls for comment.
