Courteney Cox admitted Matthew Perry "relied" on being funny while filming "Friends."
The "Friends" star opened up about her relationship with the cast and how much "pressure" Perry put on himself to make the studio audience laugh in a recent interview.
"That was a lot of pressure he put on himself," Cox, 57, told the Sunday Times. "That's a lot to think how much he relied on that for his own self-worth."
"He just struggled for a while. I think he's doing great now."
Cox reunited with Perry, Jennifer Aniston, David Schwimmer, Matt LeBlanc and Lisa Kudrow for the "Friends: The Reunion." The reunion special was hosted by James Corden and aired in May.
Cox told the Sunday Times that she would never get bored talking about her experience filming "Friends."
"No, that was such a huge part of my life," she said. "It was such a lucky situation that I fell into the show, and I went through so many things in those 10 years."

Perry is set to open up about the struggles he's gone through throughout life in an upcoming memoir. "Friends, Lovers, and the Big Terrible Thing" is set to be released in November.
"So much has been written about me in the past," Perry began his social media announcement. "I thought it was time people heard from me."
"The highs were high, the lows were low," the 52-year-old actor admitted. "But I have lived to tell the tale, even though at times it looked like I wouldn’t. And it’s all in here. I apologize it’s not a pop-up book."
