Who would have thought that Forbes' top-earning woman in music is so stingy?

Apparently, a former personal assistant of Lady Gaga is saying just that on her nine-page lawsuit filed on Dec. 14 in the U.S. District Court in New York. Not only is the singer a "Monster" for music but she's literally a Monster for money as well.

Jennifer L. O'Neill worked for the pop superstar for four weeks on early 2009 and weeks from Feb. 5, 2010, to March 5, 2011. Her duties included "confirming Defendant principal's (Lady Gaga) schedule with said principal (Mermaid Touring Inc., a company representing Lady Gaga); reviewing and reconciling Defendant' credit card statements; ordering meals and ensuring they were correctly prepared and served at specific times; maintaining the principal's personal supplies; ensuring the availability of chosen outfits; ensuring the promptness of a towel following a shower; and serving as a personal alarm clock to keep Defendant's principal on schedule." If that alone was Lady Gaga's schedule, people would wonder what Donald Trump's assistant would have to go through each day.

During the time that O'Neill worked for Lady Gaga, she attended to her needs "not only in her home, but also during her travels for her global concert tours, from city to city throughout the world, at locales including stadiums, private jets, fine hotel suites, yachts, ferries, trains, and tour buses." Talk about being a personal assistant.

The complaint also stated that the former personal assistant received a salary of $1,000 per week in 2009 and an annual salary of $75,000 for the rest of the time that she worked for Lady Gaga. But these figures only covered the regular 40-hour workweek of O'Neill and did not cover the premium she should have received for the additional 7,168 hours she worked overtime.

For being "always behind the scenes, and figuratively, if not literally, always at her (Lady Gaga's) side," O'Neill seeks an amount no less than $393,014 for her unpaid overtime wages and other fees.

A rep for Lady Gaga told E! News that "Jennifer O'Neill's lawsuit is completely without merit."

Who would blame her? She wasn't paid enough and Lady Gaga was surely "overworking" her assistant.
