Matthew Perry says his Friends co-star Jennifer Aniston confronted him about drinking problem during his career.
The actor recently opened up about how he 'nearly' died from heavy drug use.
He said his co-star confronted him about his scary drug and alcohol use at the height of his career and praised her for being a good friend.
In a preview for his interview with Diane Sawyer, which airs on October 28, Matthew says that Jennifer told him: "We know you’re drinking".
"Imagine how scary a moment that was,” he said. "She was the one who reached out the most, you know. I’m really grateful to her for that."
In the same interview, the Chandler Bing actor talked about how he once privately spent weeks in a coma after misusing opioids.
He said his family were told the star had only had a 2% chance of pulling through, following a relapse amid his battle with drug and alcohol addictions.
The star said that at one point during Friends' 10-year run, Matthew recalls taking 55 Vicodin a day and his weight dropping down to 128 pounds but yet he 'didn't know how to stop'.
Matthew said that he had to use a colostomy bag for nine months following the near-death experience.
He has undergone a total of 14 surgeries on his stomach and says the scars from the operations act as a reminder to stay sober.
He actor spent weeks in a coma, after overusing opioids caused the star's colon to burst at the age of 49.
"The doctors told my family that I had a 2 percent chance to live. I was put on a thing called an ECMO machine, which does all the breathing for your heart and your lungs. And that's called a Hail Mary. No one survives that," Matthew explained.
Ahead of releasing his debut memoir, Friends, Lovers and the Big Terrible Thing, Matthew said: "I had to wait until I was pretty safely sober — and away from the active disease of alcoholism and addiction — to write it all down. And the main thing was, I was pretty certain that it would help people."
Matthew's first experience of opioids was back in 1997 which was three years on from Friends premiering and becoming a global hit.
He had suffered an injury following a jet ski accident.
He said the prescription pills made him feel 'better than I ever felt in my entire life' before he developed a 'big problem' and checked into a rehabilitation centre for the first time in 1997.
In 2001, Matthew checked into rehab once again for addiction to Vicodin, methadone, amphetamines, and alcohol.
