Little House on the Prairie star Charlotte Stewart has opened-up about the "free love" of the 1970s.

The actress, who played much loved schoolteacher Miss Beadle in the '70s Western drama, was speaking following the release of an autobiography.

"We were in the late '60s, early '70s, when I went through a lot of the harder stuff," she told Smashing Interviews.

"Maybe there's somebody out there who has experienced the same thing, and maybe they aren't able to face it or talk about it. I've come to terms with it. I did what I had to do at the time.

"The '70s were an exploratory time with the women's movement, the free love, and there was lots of marijuana and drugs.

"I was in my early 20s and an actress in a town where there were many nice looking men available. They were interested. I had a wonderful time, and I have no regrets."

The actress revealed she had to sign a nondisclosure agreement for the long-awaited new series, saying: "I did. We all did. All 217 people in the cast. I couldn't tell you anyway because I never saw a script, just my part. None of us saw anyone else's part.

"That's the way it was when we did the original Twin Peaks. For at least the first five episodes we shot, we were fine. We all got scripts. We all got to hang out on the set and do all that.

"Then suddenly, when it hit the air and all hell broke loose, everybody wanted to know who killed Laura Palmer and what was going on. We were sworn to secrecy, and we stopped getting scripts. That's just the way it was."

She added: "I think everybody is behaving very well. I've seen absolutely nothing. They've finished shooting. It's all wrapped. It's all in the can. Sunday will be our big cast party, so my husband and I are driving down to LA. That'll be fun."

Twin Peaks will return to our screens in 2017.
