Omar Epps Sued by Nanny

Omar Epps and his wife got a sweet deal on their nanny, getting her to tidy up the house and clean up after their pets too, without paying her a dime of overtime ... according to the former employee.

Alba Hernandez says she put in 8 years with Omar and his wife Keisha ... taking care of their 2 kids. But she says she also ran errands for the Epps fam and took care of their pets.

Alba says her household duties required way more than your average 9 to 5. She says she put in more than 40 hours a week, but never got any overtime. She admits she made decent money ... $65k per year, but clearly feels she would've made much more on an hourly rate.
