Lady Gaga is seen leaving her hotel along with her dog Asia in Toronto on July 8, 2014. She signed autographs and took pictures with fans who were waiting outside her hotel.

Lady Gaga’s former assistant Jennifer O’Neill has signed with Atria Books to write a tell-all book about the musician.

Page Six first reported news of the deal, which an Atria spokesperson confirmed.

Lady Gaga, Ex-Assistant Lawsuit Ends in Settlement

O’Neill worked for Gaga from 2009-11, when the singer was on her Monster Ball tour. In 2011, O’Neill sued Gaga for $393,000 in overtime back pay. The court case provided a hint of some of the things O’Neill might spill about her former boss, including being required to share a bed with Gaga because she didn’t like sleeping alone and being woken in the middle of the night to change the DVD in the player because Gaga didn’t feel like doing it herself.

In a deposition, Lady Gaga, whose real name is Stefani Germanotta, called O’Neill a “f–ing hood rat who is suing me for money that she didn’t earn.”
