The 'Bad Romance' singer attacks her ex-employee over claims of 7,000 hours of unpaid overtime.

Lady Gaga has launched an attack on her former personal assistant after it was revealed she was being sued for $400,000 in unpaid overtime.

The 'Marry The Night' singer spoke about the false allegations during a six-hour testimony, which has been printed by the New York Post.

Jennifer O'Neil worked for the US star during 2009-2011 and said she was poorly treated during her time.

"Jennifer thinks she's just like the queen of the universe...[but] in my work and what I do, I'm the queen of the universe every day," she is reported to have said. "I'm quite wonderful to everybody that works for me, and I am completely against to what a disgusting human being you have become to sue me like this."

During O'Neill's claims, she said she was treated like a "slave" and rarely slept do to the actions of the singer.

"She slept in Egyptian cotton sheets every night, in five-star hotels, on private planes, eating caviar, partying with Terry Richardson all night, wearing my clothes," continued Gaga.

She even attacked the manner of O'Neill's behaviour on board her private jet.

"Jennifer was the first person that never offered the bed to anybody and always took it for herself," she added. "And she said, I need my three pillows so I can sleep. I heard it. I immediately was so sick by it and upset I turned over and went back to sleep."

The 'Telephone' singer also went on to suggest she employed the 75,000 a year assistant as a favour due to poor qualifications.

Meanwhile, Lady Gaga is currently touring the US on her 'Born This Way Ball' world tour and received a visit from Rolling Stones guitarist Ronnie Wood this past week at her gig in New Jersey.
