India, Sept. 20 -- Actor Charlie Sheen has opened up about Matthew Perry's struggles in the months before the Friends star's death in 2023. Speaking on Piers Morgan Uncensored, the 60-year-old actor said he noticed troubling signs while Perry was promoting his 2022 memoir Friends, Lovers, and the Big Terrible Thing. "I could tell he wasn't sober, talking about a book that is all about sobriety and recovery," Sheen said. He recalled listening to a clip from Perry's audiobook. "He didn't have that perfect, laser-focused diction he always had. I could hear a man who was handicapped," Sheen added. The actor admitted he regretted not reaching out. "I didn't know Matthew that well, but I read his book in a day and loved it. I'm in his book too - he writes, 'Eff Charlie Sheen and I'm going to be that famous one day too.' I wanted to reach out, and I didn't. He died about three weeks after I read it." Sheen, who is currently promoting his own memoir The Book of Sheen and a Netflix documentary, said he related to Perry's battle with addiction. "I could feel the prison he put himself in," he said. Perry was found unresponsive at his Los Angeles home in October 2023 and pronounced dead the same day at age 54. A toxicology report confirmed he died from the "acute effects of ketamine". HTC...
