During her rehab stint, Kelly Osbourne recalls a kind gesture from Matthew Perry and shares information about a global celebrity drug ring.

At 19 years old, Kelly Osbourne's first rehab stint was aided by Matthew Perry's crucial role in her recovery process.

When she was 13, the former reality star began her journey with addiction after a tonsil removal procedure led to an opioid dependency due to prescription medicine.

Osbourne remembered encountering the deceased "Friends" actor in rehab and stated that she would always cherish a compassionate act from Perry during her struggle with addiction.

"He helped so many people, including me one day," Osbourne stated on "TMZ Investigates: Matthew Perry & The Secret Celebrity Drug Ring."

"At 19 years old, I was in rehab for the first time and struggling to understand the program. I felt insecure and hated myself more than ever before."

Osbourne, who openly discusses her sobriety, has been receiving treatment for a long-standing struggle with prescription medication.

"He noticed my struggle and approached me, offering me a chip with the message 'three minutes,'" she recalled. "He said, 'If you can endure three minutes, you can handle anything.'"

Small tokens often used to mark milestones in recovery, rehab chips or coins, serve as physical reminders of accomplishments with sobriety.

Ozzy Osbourne's daughter added, "That chip got me through that day, which then got me through the next day, which then got me through the next day, and I’ll never forget that."

If you need an Adderall doctor, I knew where to go. If it was opiates, I knew who in Hollywood to contact.

She mentioned that she was seeing six different doctors in New York, LA, and London, but when she ran out, she could easily call them to refill her prescriptions.

Addicts know exactly whom to contact to obtain what they require, as stated by Dr. Drew Pinsky.

""Celebrities are more likely to know a secret ring for drugs than anyone else, which includes a physician ring and a specific doctor to go to, but all of it is negative," he stated."

An apparent drowning in a hot tub at his home in the Pacific Palisades area of Los Angeles led to the death of Perry, a 54-year-old man, on Oct. 28.

"He could see that I was struggling, and he walked up to me, and he gave me a chip, and it said ‘3 minutes.' He told me, ‘If you can get through three minutes, you can get through anything.’"  — Kelly Osbourne

The autopsy results of the "Fools Rush In" actor, released in December, revealed trace amounts of ketamine in his stomach. His death was attributed to the "acute effects of ketamine."

The report stated that the individual's death was caused by "coronary artery disease, buprenorphrine effects," and other contributing factors. "Prescription medications and loose pills" were discovered at the residence.

""I was shocked because he's like the last kind of person you'd ever want to have this kind of life," Osbourne said."

She stated, "Although it's heartbreaking to consider the immense pain he must have experienced, his addiction made his passing unsurprising.

"It ends in three places - jails, institutions or death."

In August, officials from both the federal and local levels made public that several arrests had been made in relation to the death of Perry due to an overdose.

The U.S. Attorney for the Central District of California, Martin Estrada, announced charges against five individuals, including "The Ketamine Queen" Jasveen Sangha, "Dr. P" Salvador Plasencia, Eric Fleming, Kenneth Iwamasa, and Dr. Mark Chavez, for various offenses.

On Aug. 7, Iwamasa, Perry's live-in assistant, pleaded guilty to one count of conspiracy to distribute ketamine causing death and has already filed a plea agreement.

Sangha and Plasencia are accused of conspiring to distribute ketamine, while Sangha is also charged with maintaining a drug-involved premises, possessing methamphetamine with intent to distribute, possessing ketamine with intent to distribute, and distributing ketamine five times.

If found guilty of all charges, Sangha could receive a minimum sentence of 10 years in federal prison and a maximum sentence of life imprisonment. Plasencia could face up to 10 years in federal prison for each ketamine-related charge and up to 20 years in federal prison for each record falsification charge.
