*A former worker for Mariah Carey is suing the singer over claims she had to work seven days a week without meal breaks or fair pay.

Ylser Oliver, 49, says she pulled 16-hour days for the artist starting in March 2007 — on tasks ranging from tidying up her Tribeca living room to packing her suitcases with performance gear and tending to her “personal needs,” according to the suit filed in Manhattan federal court and reported by Page Six.

But despite her hard work, she claims she was never paid a penny of overtime.

Before Oliver quit in June 2014, she was also tasked with answering phones, grocery shopping, “caring for” the singer’s friends and family and arranging for services and repairs to Carey’s home.

“My client put her family’s life on hold while tending to Mariah Carey’s family, and Mariah repaid her by underpaying her,” said her lawyer, Matthew Blit.

He added, “My client is a very hardworking woman who treated Mariah and her family like her own, working all hours of the day and night. Even celebrities are required to abide by the law.”

Oliver is suing for a “significant amount of money,” but Blit refused to give a dollar amount.

She was entitled to time-and-a-half pay when working more than 40 hours a week, the suit states.

“[Carey] should have been aware that . . . the practices were unlawful,” the lawsuit states.
