A ghoulish Luigi Mangione fangirl has claimed she would kill her own mom if she became a healthcare CEO, after The Post revealed that her mother is an executive for CVS Health.

Lena Weissbrot, 32, made the shocking claims on her Instagram story in the wake of The Post’s unveiling of her as the daughter of 57-year-old Reina Natero, who oversees prescription drug insurance coverage rules at the healthcare giant.

Weissbrot, who coldly proclaimed that slain UnitedHealthcare CEO Brian Thompson’s grieving kids “are better off without him” outside a court hearing for Mangione Monday, first denied that her mother was a healthcare executive.

“She’s a worker,” she said in the text message, a screengrab of which she posted on her Instagram story on Saturday night.

“If my mom was a health insurance executive I would have shot her myself,” she callously added, before going on to expand on her point.

“If she were a health insurance executive like Brain [sic] Thompson, and I were the same person I am now and if I knew what I do now (unlikely because coming from and [sic] ultra wealthy family would make me a fundamentally different person), and I were still in the will and thought I could get away with it, I’d inherit the money and redistribute to all the families she destroyed with her murderous company,” Weissbrot wrote.

“But that’s so far from my reality it’s just a fantasy. A fantasy that makes me… wet,” she added.

“Debating: would I actually redact my mom if she was a health insurance CEO,” Weissbrot wrote in the overlay text on her Instagram story.

“When it comes to debating me about hypothetical situations that don’t exist: don’t.”

Weissbrot is one of three self-styled “Mangionistas,” a trio of fangirl “journalists” who rocked up to the New York State Supreme Court with their City Hall-approved press passes to cover Mangione’s pretrial hearing.

The game developer, rapper, and maker of erotic art wrote and starred in a music video in June in which she mocked the death of father-of-two Thompson.

“The CEO’s a parasite and now they getting shot up,” she rapped while wearing a bikini in the disturbing “Toolie Toolie” video, which was posted on Vimeo.

Weissbrot did not respond immediately to requests for comment.

Weissbrot was one of several crazed fans of the accused killer Mangione who got press passes from City Hall to cover his court hearings.

She writes for the Bicoastal Beat, a website she founded, and wrote several stories about Mangione’s pretrial hearings in December.

Weissbrot went viral Monday after declaring that Thompson’s young children “are better off without him” outside the court.

“They need to learn to not be like their dad — and enjoy the blood money,” she added.

Ashley Rojas, another so-called “Mangionista,” told reporters, “F–k Brian Thompson, I don’t give a flying f–k he died.”

So extreme was her rhetoric that even left-wing New York Mayor Zohran Mamdani was forced to condemn them.

“Those three individuals should not have received press passes,” Mamdani told reporters at an unrelated press conference on Tuesday.

“My administration is reviewing the entire process and the standards for press credentialing,” he added.
