Matthew Perry has admitted to harboring grudges against Keanu Reeves.

In his new memoir, Friends, Lovers, And The Big Terrible Thing, the Friends actor took aim at Reeves, detailing his struggles with alcohol and painkiller addiction.

Perry’s first dig at the Matrix star came while discussing the death of River Phoenix, Reeves’ close friend before his death at the age of 23. Perry also co-starred in the 1988 film A Night in the Life of Jimmy Reardon with Phoenix.

“How come original thinkers like River Phoenix and Heath Ledger die, but Keanu Reeves lives on?” Perry wrote in his memoir

Later in the book, when writing about Chris Farley, the Saturday Night Live star who died of an overdose in 1997, just after the pair shot the Christopher Guest film Almost Heroes, the Chandler Bing actor made a similar dig.

“When I found out,” he wrote, “I punched a hole through Jennifer Aniston’s dressing room wall,” before adding, “Keanu Reeves walks among us.”

Perry’s choice to target Reeves in particular is unclear, given that the two have never formally worked together.
