A singer has filed an anonymous lawsuit claiming that she was repeatedly sexually assaulted by a producer, starting at the age of 14.

The lawsuit does not name either the alleged perpetrator or the woman but does describe that she had signed a seven-album deal after recording her debut in 2005.

She describes the entertainment company - also not named in the lawsuit - as being 'one of the most beloved, best-known and most valuable companies in the history of the world,' TMZ reports.

The singer explains in the suit that she was then introduced to the man who would become her day-to-day producer, mentor and agent.

And while things started off smoothly, the woman soon noted that the perpetrator's attitude changed. She claims that the man became controlling and the nature of their relationship changed.

She says that he began telling her he loved her and described her as being his soulmate. While he was telling her these things, the singers claims that he was also making negative comments about her weight and looks.

The victim alleges that the producer would rub and fondle her genitals and body. She says he would also digitally penetrate her and would orally copulate her as well, forcing her to do the same on him.

The woman also says that they had intercourse, both vaginally and anally. She asserts that the man even drugged her before they had anal intercourse.

She also states that the man would spend time with her mom in an effort to 'groom' her.

Abuse was said to have lasted for two years, with incidents said to have taken place at the Staples Center and on set for a music video at Warner Bros. The victim also claims that altercations would occur in hotels, cars, public streets and other places.

The lawsuit also names people that the woman claimed acted as enablers.
