Matthew Perry's 'Ketamine Queen' Has Famous Hollywood Junkies 'Quaking in Boots': A-List Addicts 'Panicking They'll Be Named in Plea Deal'

Tormented Matthew Perry 's alleged drug dealer, Jasveen 'Ketamine Queen' Sangha , has sparked fears she could expose her A-List clientele in a bid to cop a plea deal and stay out of prison.

The self-described "artist and singer" was one of five people arrested in a major probe following the death of the Friends star from the acute effects of horse tranquilizer ketamine.

RadarOnline.com can reveal insiders claim that she may be willing to expose her roster of famous clients in order to save her own skin, causing panic across Hollywood.

An insider said: "There is widespread panic over who else can be dragged into this case. She catered to a lot of famous people, and they could all easily be collateral damage."

Sangha is currently behind bars for her suspected role in the death of the beloved Friends star, as well as another potential trial in the death of another man.

She was charged with nine crimes in total, including the distribution of the ketamine that resulted in Perry's death at 54 last fall.

Sangha brazenly showed up to court dressed in a Nirvana t-shirt as she pled not guilty.

The insider has revealed any celebrities associated with Sangha could panic – leading to the possibility of even more deaths.

Images were reportedly uncovered of her living it up with clients all over the world in nightclubs and exotic parties.

Dr. Salvador Plascencia , Dr. Mark Chavez, Perry's live-in personal assistant Kenneth Iwanasa , and the star's pal Erik Fleming were also charged.

Fleming, 51, Iwanasa, 59, and Chavez, 46, have agreed to plea deals. Plascencia, 42, pleaded not guilty and was released on a $10,000 bail.

Sangha has reportedly bragged to authorities she has her roster of celebrity clients on speed dial.

Her famous clients could be compromised as part of a "broad undercover investigation" into Hollywood's drug world.

Court documents have revealed Sangha, 41, often referred to some of her famous clients in text messages as "only small fish". She also reportedly stored drugs inside her home.

Other items seized in the raid of her mansion included cash stashed in paper bags labeled "Ketamine for S", drugs, prescription bottles and a counterfeit letter from Plascencia.

Following Perry's death, Sangha was hit with additional charges and is still being held on a $250,000 bail.

On Tuesday, a Los Angeles federal judge set a March trial date for Sangha and Plascencia.

A pretrial hearing will take place in February.

Perry was found dead on Oct. 28 in the hot tub at his Pacific Palisades home.

The medical examiner ruled ketamine was the primary cause of death .

Prosecutors said Perry obtained the ketamine illegally through a network that included Plascencia, Chavez, his assistant and Sangha.
