Michelle Pfeiffer revealed that she was in a cult when she was in her 20s.

In an interview with Telegraph's Sunday Stella Magazine, the actress revealed that she was under the influence of a cult when she was starting out. She fell in with a couple she described as "very controlling." The cult believe in breatharianism- a belief that people can survive without food or water and relies only in sunlight for nourishment.

"They worked with weights and put people on diets. Their thing was vegetarianism," she told the magazine while she was promoting her movie, The Family. "They were very controlling. I wasn't living with them but I was there a lot and they were always telling me I needed to come more. I had to pay for all the time I was there, so it was financially very draining."

"They believed that people in their highest state were breatharian," she added.

She said that she realized what was happening when she met her first husband, actor Peter Horton who was cast in a film about the Moonies, the name given by the followers of Sun Myung Moon. While they were researching about the cult, she recognized, "I was in one."

"We were talking with an ex-Moonie and he was describing the psychological manipulation and I just clicked," she mentioned in the interview.

She decline to mention the name of the couple but said that they were personal trainers.

Pfeiffer's The Family also featuring Robert De Niro and Tommy Lee Jones opens in the U.K. on Nov. 22. It was already released in the U.S. last September.
