Lady Gaga's former assistant is reportedly writing a tell-all book about working for the star.
Jennifer O'Neill - who previously sued the singer, alleging she cheated her out of overtime wages - has signed a deal with Simon And Schuster imprint Atria Book.
She is now working on a book called Fame Monster, according to the New York Post's Page Six.
Atria Books' vice president and director of publicity Paul Olsewski has confirmed the book deal.
In 2011 O'Neill brought a lawsuit against Gaga claiming she was on call 24 hours a day, seven days a week, when she worked for the star for one to two months in early 2009 and for 13 months beginning in February 2010.
She had said in a deposition that if Gaga was watching a DVD in the middle of the night and grew tired of it, she woke her up to take it out and replace it.
"Every day is a work day for her, so every day is a work day for the rest of us," she said.
In her deposition evidence, Gaga said: "You don't get a schedule that is like you punch in and you can play ... at your desk for four hours and then you punch out at the end of the day. This is when I need you, you're available."
The singer also referred to her former employee as "a f***ing hood-rat who is suing me for money that she didn't earn".
However, in 2013 the pair settled their differences out of court and the terms of the deal were not disclosed.
