The hooker accused of fatally drugging three johns — including Cipriani Dolci head chef Andrea Zamperoni — is being investigated in at least two more deaths, law-enforcement sources told The Post on Friday.

Queens prostitute Angelina Barini is being eyed in the two additional fatal overdoses as well as up to six other grand-larceny cases, the sources said Friday.

Barini, 41, has been accused of plying Zamperoni and the other victims with a fentanyl-laced drug cocktail and then robbing them once they lost consciousness.

The femme fatal was arrested on drug charges after the discovery of Zamperoni’s body inside the Kamway Lodge & Tavern in Elmhurst, Queens, last month. She’s now facing a federal charge of conspiracy to distribute and possession with intent to distribute one or more substances containing fentanyl.

Earlier Friday, NYPD Chief of Detectives Dermot Shea told reporters that Barini was still under investigation, including for a fourth death. The Post’s sources said she is being eyed in not just a fourth but a fifth fatal overdose as well.

“What we do know is there’s a history here with Angelina,” Shea said. “We believe she is going to locations with men and stealing property after they pass out.”

A lawyer for Barini did not immediately return a message.
