After receiving backlash for insulting Keanu Reeves in his memoir "Friends, Lovers, and the Big Terrible Thing," Matthew Perry announced Saturday that he would be removing the actor's name from future editions of the book.

According to New York Post, Perry, 53, made the apology during his appearance at the Los Angeles Times Festival of Books.

"I said a stupid thing. It was a mean thing to do," said Perry, adding that he only pulled Reeves' name because he lives on the same street.

The "Friends" star then noted: "I've apologized publicly to him. Any future versions of the book will not have his name in it... If I run into the guy, I'll apologize. It was just stupid."

In his memoir, Perry said several times that the "John Wick" star was an actor who "still walks among us" despite the fact that "the original thinkers like River Phoenix and Heath Ledger die."

Perry also mentioned that he was in the 1988 movie "A Night in the Life of Jimmy Reardon, working with the late River Phoenix, who was close to Reeves.

In addition to being close friends in the movie, the two became real-life pals until Phoenix's untimely death from a drug overdose in 1993 at the age of 23.

Matthew Perry Apologized in the Past for Adding Keanu Reeves to His Book

Matthew Perry has previously expressed remorse for insulting Keanu Reeves in his book. Perry also issued an apology last October, telling PEOPLE magazine in a statement that he misspoke.

"I'm a big fan of Keanu," Perry said, adding that he chose a random name, which was a mistake. "I apologize. I should have used my name instead," he noted.

The actor's struggles with alcohol and drugs, which resulted in repeated hospital admissions and trips to rehab, were detailed in Perry's memoir "Friends, Lovers, and the Big Terrible Thing," released in November, USA Today reported.

Matthew Perry shared his experience with sincerity and humor, entertaining behind-the-scenes anecdotes and details about his decades-long battle with addiction.

"There is light in the darkness," Perry wrote in his book's prologue. "You just have to look hard enough to find it."

Matthew Perry's Alcohol and Drug Addiction

Matthew Perry's alcoholism was in its early stages when he was cast in "Friends" at age 24.

"I could handle it, kind of. But by the time I was 34, I was entrenched in a lot of trouble," he told PEOPLE.

However, there was a period during which he maintained sobriety. He made it through the entirety of Season 9 sober, he noted.

During "Friends" heyday, Perry reportedly dropped to a scary 128 pounds while using 55 Vicodin daily.

"I didn't know how to stop," he said. Perry noted that he would start packing if the cops showed up at his door to take him if he had another drink.

He also said the progression of the disease and the addiction made it impossible for him to quit.

"So it gets worse and worse as you grow older," Perry noted.
