Charlie Sheen revealed his thoughts on Matthew Perry's well-being right before his death from excessive ketamine administration. In a Tuesday, September 16, interview on YouTube's Piers Morgan Uncensored, Sheen, 60, said he "could see" Perry promoting his 2022 book on beating addiction and believed he wasn't well. (Perry died at the age of 54 in October 2023, almost one year after his book Friends, Lovers, and the Big Terrible Thing was published.) "I could tell he wasn't sober, talking about a book that is all about sobriety and recovery," Sheen claimed to host Morgan, 60.
