Lady Gaga's former assistant, Jennifer O'Neill, is suing Mother Monster for a whole lotta unpaid overtime. And when Gaga gave a deposition, she was not only out for blood, she used more expletives than the entirety of 'Pulp Fiction.'

Tape of her sworn testimony reveals an interesting picture of the often well-spoken (if a little eccentric) Gaga. Over the course of the six-hour deposition, she refers to O'Neill as a “witch,” a “disgusting human being” and a “f---ing hood rat who is suing me for money that she didn't earn.”

Gaga accuses her prior assistant of being a self-obsessed person who thinks she's the center of all things, a “queen of the universe.”

"[Jennifer] didn't want to be a slave to one, because in my work and what I do, I'm the queen of the universe every day," Mama Monster allegedly spat during her testimony. "It is, like, such an amazing luxury that I get to travel the world and have planes. She doesn't even see what a luxury it is, but she thinks it's owed to her for no reason."

In addition to these claims, Gaga says her assistant was a lazy good-for-nothing who would sleep until noon, borrow her clothes and take over the extra bed on the plane rather than offering it to Gaga's mother or her family (something no other assistant had ever done). Worse, she hogged all three pillows. ALL THREE!

O'Neill is suing Gaga for $393,000 plus damages for 7,168 hours of unpaid overtime. Gaga says that's crap and none of her employees get paid overtime -- something Jennifer supposedly knew when she signed on.

"I'm going to give all the money that she wants to my employees that work hard for me now that deserve it," the pop star threatened during her testimony. "I'm not going to give it to her so she can go to Intermix and buy herself a new tube top."

Hope O'Neill caught that shade -- because it was definitely thrown.
