She also explained how Netflix was actually the spark for the reunion - which will also feature Jennifer Aniston, Courteney Cox, David Schwimmer, Matt LeBlanc and Matthew Perry - as the iconic show gained a new wave of popularity on the streaming platform.
She added: "To be honest, I think when it moved to Netflix and it did so well on Netflix...
"That's why Mart and David are so great. ['Friends' co-creators] Marta Kauffman and David Crane, they knew what they were doing."
The sitcom originally ran from 1994 until 2004, and Kudrow recently admitted the show - which is no longer considered to be as "progressive" as it once was - would be "completely different" if it was being made in 2020.
Asked how a Friends-style sitcom could look in the modern era, she said: "Well, it would not be an all-white cast, for sure.
"I'm not sure what else, but, to me, it should be looked at as a time capsule, not for what they did wrong.
"Also, this show thought it was very progressive. There was a guy whose wife discovered she was gay and pregnant, and they raised the child together?
"We had surrogacy too. It was, at the time, progressive."
