Kudrow took to Instagram to pay tribute to Perry and began recalling the beginnings of their sitcom which was filmed from 1994 to 2004.

"Shot the pilot, Friends Like Us, got picked up then immediately, we were at the NBC Upfronts. Then… You suggested we play poker and made it so much fun while we initially bonded. Thank you for that," Kudrow wrote.

"Thank you for making me laugh so hard at something you said, that my muscles ached and tears poured down my face every day."

"Thank you for your open heart in a six-way relationship that required compromise. And a lot of 'talking,'" she added.

Lisa Kudrow thanked Matthew Perry for 'showing up at work' when he was not well

Speaking about Perry's battle with addiction during the filming of their show, Kudrow wrote, "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. Thank you for trusting me," she added.

"Thank you for all I learned about GRACE and LOVE through knowing you. Thank you for the time I got to have with you, Matthew," the post concluded.

Lisa Kudrow wrote the foreword for Matthew Perry's memoir

Kudrow and Perry's friendship grew over the years even after the filming ended in 2004.

The foreword for Perry's memoir 'Friends, Lovers and the Big Terrible Thing' released in 2022 was written by Kudrow.

In the foreword, she called him a "whip-smart… charming, sweet, sensitive, very reasonable and rational."

"Truly, I wasn’t exactly sure how Matthew was doing,” Kudrow said of Perry's struggle which he kept as a "secret," even from her.

"Over those years I didn’t really try to intervene or confront him, because the little I knew about addiction was that his sobriety was out of my hands."

"And yet, I would have periods of wondering if I was wrong for not doing more, doing something,” Kudrow explained why she "focused on Matthew" and not his addiction.
