Charlie Sheen claimed he clocked Matthew Perry’s relapse one year before the late actor’s fatal overdose.

The “Two and a Half Men” alum alleged during an interview with Piers Morgan on Tuesday that he “could see” Perry was abusing drugs when promoting his 2022 memoir.

“I could tell he wasn’t sober talking about a book that is all about sobriety and recovery,” the Emmy nominee, 60, insisted on “Piers Morgan Uncensored.”

Sheen explained that he “felt really bad” for Perry after listening to his “Friends, Lovers and the Big Terrible Thing” audiobook.

“When I heard a little snippet … he didn’t have that perfect, specific, laser-focused diction that he always had delivering comedy or [doing] anything at the level that he did,” the Golden Globe winner recalled.

Sheen, who “didn’t know Matthew that well,” alleged that he “hear[d] a man who was … handicapped.”

Perry released his book in November 2022 — and was found dead in his Los Angeles home’s hot tub in October of the following year.

His cause of death was a ketamine overdose.

Three weeks before Perry’s passing, Sheen read the “17 Again” star’s candid book, which included a line along the lines of “F–k Charlie Sheen. I’m going to be just as famous one day.”

Sheen admitted that he “wanted to reach out” to talk about the memoir but did not do so before Perry’s death.

“I read his book, and I read it in a day, and I loved it,” he gushed. “And I’m so proud of him and inspired by it. … I could feel that sort of the prison that he put himself in.”

Earlier this month, Sheen shared a similar sentiment with Page Six about not contacting Perry over the “common ground” and “deeper truth” they shared as “veterans of the unspeakable.”

The “Book of Sheen” author, who released his memoir last week, remembered, “I was going to call him … for a cup of coffee or something. And regrettably, I didn’t.”

Elsewhere in the interview, the “Red Dawn” star shared with us that he has never tried the drug that killed Perry while battling his own addiction.

“I never did it,” Sheen said. “I knew a couple people that did and so I would see them on it. It just wasn’t a color I knew I would look good in.”

Sheen noted that he attended a support group Perry ran a few times — and the duo were at a party together when the “Anger Management” alum met his third ex-wife, Brook Mueller.

The actress, 48, became embroiled in Perry’s death investigation due to her connection with people later charged with selling ketamine to the Golden Globe nominee.

As of September 2024, Mueller was nine months sober.
