Matthew Perry's stepfather, Keith Morrison, shared a heartfelt plea one month after the actor's sudden death on Oct. 28.

"This is not the sort of thing I commonly do, this pitch," the journalist wrote Monday on X, previously known as Twitter, in his first post since Perry's death. "But this year is different. And tomorrow is Giving Tuesday. Do what you can; he would have been grateful."

Perry's family also spoke out about the legacy they hope to "honor" in the wake of the actor's passing.

"It is important to us, as a family, to honor Matthew’s legacy," Perry’s family told Fox News Digital in a statement. "The potential that the Matthew Perry Foundation has to help those suffering from this disease is something we are proud to bring to the world."

The late actor's former "Friends" co-star, Jennifer Aniston, also encouraged fans to donate to The Matthew Perry Foundation, through a post on her Instagram story. She shared a post from the foundation's Instagram account on her story, which featured a photo of Perry, and the quote, "addiction is far too powerful for anyone to defeat alone. But together, one day at a time, we can beat it down."

"For #GivingTuesday please join me and Matty's family in supporting his foundation - which is working to help those suffering with addiction," she captioned the post, adding "he would have been grateful for the love." 

The foundation was created Nov. 3 in Perry's honor to help people struggling with addiction, much like the actor did before seeking a sober lifestyle. "The Matthew Perry Foundation is the realization of Matthew's enduring commitment to helping others struggling with the disease of addiction," the mission statement said. "It will honor his legacy and be guided by his own words and experiences and driven by his passion for making a difference in as many lives as possible."

Perry died Oct. 28 from an apparent drowning at his California home, law enforcement sources previously confirmed to Fox News Digital. He was 54.

His autopsy was completed Oct. 29, and his cause of death was listed as "deferred," pending toxicology results, by the County of Los Angeles Department of Medical Examiner.

It is unclear when an official cause of death will be released. Toxicology tests can take up to three to six months to complete, the medical examiner's office told Fox News Digital.
