Lisa Kudrow admits becoming real life friends with her 'Friends' co-stars was "hard" work

Appearing on Dax Shepard's 'Armchair Expert' podcast, she confessed the "six-way relationship took some work", and the group "worked hard at being friends".

Over the 10 seasons, the castmates became genuine pals away from the camera, and so they would try to "really talk things through" if there were any disagreements.

She recalled: "If someone said something or did something, it didn't get too big because it was, "Can I talk to you?' "

Lisa admitted it was "usually not her" who would open up the conversations, because she "never knew that was allowed" in terms of having straightforward chats in that way.

She added: "I had to learn to be like, 'Can I talk to you about something?' "

The series initially ran over the course of 10 seasons, but now streams on Netflix and is now considered to be a billion-dollar franchise thanks to endless reruns and merchandise lines.

The 'No Good Deed' star recently noted that the interaction between the six main characters is the reason that fans around the globe are "still attached" to them all these years later, and that the sitcom has all the other magical ingredients that synchronise together to make a worthwhile program.

She told PageSix: "That's why people get attached to them and then if it's funny, there [are] good performances, good jokes, that's a bonus and 'Friends' had all that."

The 'Comeback' star even noted that many had raised concerns at the time that the show was nothing more than a"bunch of young people sitting on a couch talking" but didn't really have to worry about that because she was simply part of the cast.

She said: That's not my problem. I'm just in it, but yes it was a show!"
