Madonna has said that disgraced Hollywood producer Harvey Weinstein "crossed lines and boundaries" when they worked together in the 1990s.
The pop icon is the latest star to accuse Weinstein of unwanted sexual advances.
In 2017, the once-powerful movie producer was rocked by scores of allegations of sexual misconduct, including rape. He has denied the allegations.
Madonna and Weinstein worked together on her tour documentary Madonna: Truth or Dare in 1991, which was distributed by Weinstein's former company Miramax.
The 60-year-old singer has now spoken about Weinstein and the Time's Up movement in an interview with The New York Times.
She said she thought it was "pretty surprising" that an anti-sexual assault movement would become mainstream in her lifetime, before describing her experience with working with Weinstein.
"Harvey crossed lines and boundaries and was incredibly sexually flirtatious and forward with me when we were working together; he was married at the time, and I certainly wasn’t interested," she said.
Madonna said she knew he behaved similarly with her peers in showbiz, and that the attitude was "you have to put up with it".
"I was aware that he did the same with a lot of other women that I knew in the business. And we were all, ‘Harvey gets to do that because he’s got so much power and he’s so successful and his movies do so well and everybody wants to work with him, so you have to put up with it.' So that was it."
The popstar also explained that when she first heard about the allegations against Weinstein in October 2017, her reaction was "finally".
"So when it happened, I was really like, 'Finally.' I wasn’t cheering from the rafters because I’m never going to cheer for someone’s demise. I don’t think that’s good karma anyway.
"But it was good that somebody who had been abusing his power for so many years was called out and held accountable."
