Ostriches don’t fly — and neither did this one-time beauty queen’s lawsuit against her ex.

A Manhattan judge nixed a “collateral attack” by former Miss Germany International Aline Marie Massel, who accused her married ex-lover of promising her a Ugandan ostrich farm, only to allegedly give her a sexually transmitted disease.

Manhattan Supreme Court Justice Barbara Jaffe tossed Massel’s lawsuit against Autonomy Capital CEO Robert Charles Gibbins late Wednesday because the woman’s claims had already been rejected by a UK judge.

Justice Jaffe found that “she does not show that she attempted to seek appropriate relief from the British court and offers no authority for the proposition that she is entitled to relief via a collateral attack” in the New York court.

The beauty queen-turned-Tesla model met Gibbins in Manhattan in June 2014. Massel claimed Gibbins told her he was unmarried and promised to “buy a large estate for them in Canada called the Royal Antler … and an ostrich farm in Uganda.”

They split after he allegedly gave her HPV, according to her 2017 Manhattan Supreme Court suit.

In March, a British judge determined that Massel’s STD claims were not credible because she never submitted medical tests proving the allegation.

Meanwhile, Gibbins accused Massel of faking a pregnancy and then demanding $4.2 million to get an abortion.

A rep for the London-based hedge funder said Jaffe’s “decision confirms that Ms. Massel and her attorneys only sought to extort Mr. Gibbins and spread vicious lies about him in the process.”

Eddie Hayes, Massel’s attorney, said, “Women are at a terrible disadvantage in England because the proceedings are secret and usually only the man can pay the legal fees.”
