Twiggy Ramirez, bassist for rock band Marilyn Manson has been accused of rape by Jessicka Addams, lead singer in the band Jack Off Jill.

Addams detailed the alleged assault in a lengthy Facebook post, writing that she and Ramirez entered into a relationship in 1990s, when she was 18, and it became physically violent in the following months and years, reports variety.com.

She detailed a pattern of abuse that began with jealousy and escalated into hitting her repeatedly.

During a tour break with Nine Inch Nails, who Ramirez also played with, the musician allegedly visited Addams at their friend Pete's apartment.

"He forced me on to the floor with his hand around my neck. I said NO. I said it so loud enough, that Pete came rushing in from the other room to get him off of me. But I had been raped. I had been raped by somebody I thought I loved," Adams posted.

Addams attributed her delay in coming forward with the accusation to warnings from her label that if she went public, her band could likely get black balled by "concert promoters, radio programmers, and other bands and their managers."

"The label blatantly feared the big machine behind Marilyn Manson would use their power to destroy not only Jack Off Jill, but my name, Jessicka, as well. The pressure and guilt of the inevitable repercussions of my rape story affecting my band's livelihood, happiness and success kept me silent for years," she added.
