Perry died Oct. 28 last year from acute effects of ketamine. He was 54. Perry's personal assistant and an alleged San Fernando Valley drug dealer known as "The Ketamine Queen" were among the five people charged in August for distributing ketamine to Perry during the final weeks of his life.

Aniston and Perry co-starred on all 10 seasons of the hit NBC sitcom Friends, centered on six close-knit pals navigating life and love in New York. The series, which ran between 1994 and 2004, also starred Courteney Cox, Lisa Kudrow, Matt LeBlanc, and David Schwimmer.

News of Perry's sudden death sent shockwaves across Hollywood last year. His tight-knit Friends costars issued a joint statement about the "unfathomable loss" before sharing their own homages. In her own tribute last year, Aniston said the loss of her "little brother" Perry has "cut deep."

"Having to say goodbye to our Matty has been an insane wave of emotions that I’ve never experienced before," wrote Aniston on social media. "We all experience loss at some point in our lives. Being able to really SIT in this grief allows you to feel the moments of joy and gratitude for having loved someone that deep. And we loved him deeply.”

Added Aniston, "Matty, I love you so much and I know you are now completely at peace and out of any pain. I talk to you every day… sometimes I can almost hear you saying 'could you BE any crazier?'"

Speaking with Variety last December in her first interview following Perry's death, an emotional Aniston said she hopes her late costar is remembered "as he said he’d love to be remembered” — someone who lived well and loved to help others. (The actor wrote candidly about his addiction struggles in his 2022 memoir, writing in an excerpt, “When I die, as far as my so-called accomplishments go, it would be nice if Friends were listed far behind the things I did to try to help other people.”)

“I want people to know he was really healthy, and getting healthy," said Aniston. "He was on a pursuit. He worked so hard. He really was dealt a tough one. I miss him dearly. We all do. Boy, he made us laugh really hard.”
