A former personal assistant to Lady Gaga claims the singer has lived up to her album title of Fame Monster.

Jennifer O'Neill has filed a lawsuit seeking nearly $380,000 from Gaga's touring company for 7,168 hours of unpaid overtime racked up while being at the entertainer's beck-and-call in late 2009 and most of 2010.

Describing Gaga as a nightmare boss, O'Neill claims her duties required everything from acting as a "personal alarm clock" to "ensuring the promptness of a towel following a shower."

The lawsuit was filed Dec. 14 in Manhattan federal court. Reps for Gaga say the action is "completely without merit," CNN reports.– Mike Fleeman
