'Friends' cast shares memoriesof late Matthew Perry in touching tributes on Instagram

The Los Angeles County Medical Examiner's office revealed in December that Perry's cause of death two months earlier was an accident from "the acute effects of ketamine." Contributing factors were drowning, coronary artery disease and the effects of buprenorphine. Perry starred as Chandler Bing on "Friends" alongside Cox, Kudrow, Jennifer Aniston, David Schwimmer and Matt Le Blanc.

The five remaining "Friends" co-stars broke their silence in an initial joint statement two days after Perry's death.

"We are all so utterly devastated by the loss of Matthew. We were more than just castmates. We are a family. There is so much to say, but right now we’re going to take a moment to grieve and process this unfathomable loss," the Oct. 30 statement read.

Later, Cox and Kudrow shared their own individual reactions to Perry's death on Instagram.

"I am so grateful for every moment I had with you Matty and I miss you every day," Cox wrote in an Instagram caption on Tuesday, as she shared an outtake from Season 4 in which Chandler and her character Monica are revealed to have slept together while in London for her brother Ross' (Schwimmer) wedding.

"To give a little backstory, Chandler and Monica were supposed to have a one night fling in London. But because of the audience's reaction, it became the beginning of their love story," Cox wrote.

Kudrow thanked Perry for his decades-long friendship in her individual post.

"Thank you for your open heart in a six way relationship that required compromise. And a lot of 'talking.' Thank you for showing up at work when you weren’t well and then, being completely brilliant. Thank you for the best 10 years a person gets to have," Kudrow said.
