Lady Gaga Sued By Former Personal Assistant For $380,000

Lady Gaga's former personal assistant is claiming the popstar was a nightmare to work for and regularily made diva-like demands -- how shocking.

The New York Post reports that Jennifer O'Neill worked for the 25-year-old popstar for 13 months and now claims she is owed hundreds of thousands of dollars in unpaid overtime.

O'Neill alleges that for $75,000-a-year she had to cater to Gaga's every whim at any hour of the day or night. According to court papers, O'Neill was responsible for "ensuring the promptness of a towel following a shower and serving as a personal alarm clock to keep [Gaga] on schedule."

That sounds like fairly standard expectations for a celebrity's personal assistant, but O'Neill, 41, also claims in the lawsuit that there was no breaks for meals "or, at times even sleep," claiming that she had to be on hand for "spontaneous, random matters in the middle of the night."

According to the Post, O'Neill filed a lawsuit for $380,000 in unpaid overtime against Gaga's Mermaid Touring company -- estimating that she worked 7,168 unpaid hours attending to the singer. A spokeswoman for Gaga, told the paper the lawsuit is "completely without merit."

Even if Gaga is ending the year with a lawsuit, it's hardly enough to ruin 2011. The popstar is estimated to have made $90 million and it was just announced she topped Do Something's list as one of the most charitable celebs of the year.
