Charmed actress Rose McGowan has revealed that she is being blackmailed over an old tape of her having sex and allegedly taking drugs.

"Time for some adult talk. I find it deeply distasteful to discuss my personal life, but because I let the wrong person touch me, I'm in an icky situation," she tweeted. "Here's the situation. a person from my past is (via a 3rd party) now allegedly threatening to release a sex video of me and say I enjoy recreational drugs."

McGowan says it was all a part of the Hollywood lifestyle, which she has been a part of since she was a teenager.

"The truth is, I do," she confessed. "I am an adult in supposedly the 'freest country in the world.' I try to live my life by doing what I want when I want. Believe me, I've earned it. Here's the breaking news: I have lived in Hollywood by myself since I was 15."

"It is my right to live as I see fit. To do my best to not hurt nor hate," she continued. "To continue, despite ZERO reasons why to be a cheerleader for Womxn and Mxn everywhere on this planet. I may live my life differently from most, I certainly get f*cked with more than most, and maybe that's the price for living a free and full life. I don't know. What I do know is that I'm being bullied and I think blackmailed."

She did not say who was blackmailing her, but she also added that she would not be deleting her confession from Twitter.

McGowan was one of the dozens of women who stepped forward to accused exec Harvey Weinstein of sexual misconduct.
