The so-called “Ketamine Queen” accused of supplying the deadly batch of drugs that killed actor Matthew Perry is a Mafia superfan who has a website dedicated to the world of organized crime.

Jasveen Sangha, 41, who was among the five arrested Thursday in connection with the “Friends” star’s death, used the site — which was first reported on by TMZ — to boast about her “love” of the notorious underworld network.

Her obsession with the crime gang dates back to when she was young after watching the “Scarface” and “Godfather” films, according to her site’s bio page.

“Later on in high school, I decided to do a research project on the mafia and I became fascinated with the history and the many stories attached to each of America’s notorious crime families and famous gangsters,” she wrote.

The website is also broken down into subsections — including “Mafia Mug Shots,” “Famous Mafia Faces,” “Cities of Mafia Families,” “Mafia History” and “Favorite Mafia Movies.”

The emergence of Sangha’s crime-obsessed blog came soon after the alleged drug queen was slapped with a slew of charges tied to Perry’s death in October last year.

Prosecutors allege Sangha — who they said is renowned as the “Ketamine Queen of Los Angeles” — allegedly used her North Hollywood “stash house” as the distribution point for the ketamine that killed the actor.

She is accused of providing the batch of drugs to alleged co-conspirator Erik Fleming, who then sold it to Perry, according to a California federal indictment.

Sangha was charged alongside Dr. Salvador “Dr. P.” Plasencia, Dr. Mark Chavez, Perry’s personal assistant Kenneth Iwamasa, and Fleming.

The “Friends” actor was found floating face down in a hot tub in his Pacific Palisades home on Oct. 28 after overdosing on the powerful anesthetic.
