"I knew there wasn't ever a movie. There was never a Friends movie. Ever," she said. "So I've always known it's not happening."
Back in April, rumours of a reunion sent the internet into a flap. They were, of course, later proven to be false.
Chimed the show's co-creator Marta Kauffman to E! Online at the time: "I'm going to clear this up right now. No! Not happening."
She went on to explain, "Friends was about that time in your life when your friends are your family and once you have a family, there's no need anymore.
"I'd rather people go, 'Oh, please! Please!' than 'I can't believe you did that. It was horrible.'"
Kudrow admits that even she was momentarily duped by an online graphic which teased a regrouping of the cast.
She said: "With this last rumour someone came up with a great graphic with the couch and it looked like a real teaser and I went, 'Wait!' And then someone came up with a fake story and got some publication to buy the lie that there was going to be a reunion, so I saw on Twitter people were posting this article that NBC was really going to do it.
"And I went, 'Wait a minute, was I not invited? Oh my God, maybe there is one and I wasn't asked to do it'. I even had a moment where I believed it because everything around it looked real. It was a good setup."
Putting the rumours to rest, she added: "The creators have put them to rest. NBC has. I don't know who else needs to say, 'It's really not happening.'"
The 49-year-old actress recently said that she feels "too old" for a Friends reunion.
"I'm too old. I wouldn't even have an interest in seeing what those people are doing ten years later as parents that have to be responsible," Kudrow told HuffPost Live.
"It would be so different that it wouldn't be Friends anymore.
"Of course I would do it if everyone wanted to do it. And everyone isn't the six of us - it's David Crane and Marta Kauffman who created the show."
Former Friends co-star Matthew Perry also harpooned the idea of a reunion recently.
"I don't think so. It would be terrible to do something and have it not be good," he told ABC News.
"It was so terrific. If we did a movie and it sucked, then it would, you know, blemish it."
