Sangha, 42, pleaded guilty to five federal charges Wednesday, including illegally providing the ketamine that resulted in Perry's fatal overdose in 2023, according to the Associated Press. Her trial had been scheduled to begin later this month, but she reached a plea agreement in August.
She will be sentenced Dec. 10 and faces up to 65 years behind bars, though prosecutors said they will ask for less than the maximum penalty.
Sangha's attorney Mark Geragos didn't immediately respond to Entertainment Weekly's request for comment. He told reporters outside that courthouse that his client "feels horrible about all of this. Nobody wants to be in the chain of causation, for lack of a better term. She feels horrible and she's felt horrible since day one."
Per the AP, Perry's mother, Suzanne Perry, and his stepfather, Dateline reporter Keith Morrison, attended the court proceedings as Sangha answered questions about whether she knew the drugs she gave co-defendant Erik Fleming (who previously pleaded guilty) were for Perry.
"There was no way I could tell 100 percent," said Sangha, who is a dual citizen of the U.S. and the U.K. "I didn't know if all of [the vials] or some of them" were intended for Perry.
Perry was found unresponsive in a hot tub at his L.A. home on Oct. 28, 2023, and pronounced dead at the scene. He was 54.
At the time, authorities said there was no indication of foul play, and an autopsy report later determined that his death was caused by "the acute effects of ketamine," and that drowning, coronary artery disease, and buprenorphine (a medication used to treat opioid use disorder) were also contributing factors.
The autopsy report additionally noted that Perry had been receiving legal but controversial ketamine infusion treatment around the time of his death. However, because ketamine has a short half-life, the traces of the substance in his system couldn't have been from one of those treatment sessions, the report said.

The investigation into Perry's death led to Sangha and four other individuals being charged in August 2024: Kenneth Iwamasa, the late actor's personal assistant, who admitted to repeatedly injecting Perry with ketamine without medical training; Salvador Plasencia and Mark Chavez, two doctors accused of distributing ketamine to Perry; and Fleming, an acquaintance of Perry's who allegedly took on the role of middleman between the actor and Sangha.
All five defendants have now pleaded guilty in the case and are awaiting sentencing.
