A Queens woman pleaded guilty Thursday to setting up a black market butt injection that killed mother-of-two Latesha Bynum.

Allison Spence, 46, copped to second-degree manslaughter and unauthorized practice of a profession in exchange for up to eight years in prison for the deadly July 15, 2017, procedure.

Spence was working for fake doctor Kevin Richardson at an unlicensed Gramercy clinic where Bynum had the illegal injection.

When Bynum left, she developed intense chest pain and called 911. She was later pronounced brain-dead at Mount Sinai St. Luke’s hospital and taken off life support. An autopsy found that silicone had entered her bloodstream and killed her.

Richardson was sentenced to four to 12 years in prison last September after also pleading guilty to manslaughter and other charges as part of a plea deal.

Spence is due back in court March 28 for sentencing.
