Mariah Carey News: Singer Sued by Former Assistant for Thousands of Alleged Unpaid Overtime Hours

On Thursday, Mariah Carey's former assistant Ylser Oliver filed a lawsuit in Manhattan against Carey, which claimed that the "Hero" singer forced her "to work 16-hour days for six or seven days a week" without receiving compensation for her overtime work hours, Yahoo! Celebrity reports.

Oliver's lawyer Matthew Bilt is requesting that Carey pay Oliver back her wages as well as her attorney's fees.

Though Oliver does not specify the the amount she is seeking in the lawsuit, Yahoo! Celebrity suggests that "a conservative estimate concludes" that Carey's ex-assistant might be seeking "at least 4,224 hours of overtime pay."

"My client put her family's life on hold while tending to Mariah Carey's family, and Mariah repaid her by underpaying her," Bilt told Page six about Oliver's recent lawsuit. "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, who worked for Carey from March 2007 to June 2014, tended to Carey's professional and personal needs–including numerous tasks ranging from traveling with Carey, answering phone calls, providing personal shopping services, packing up Carey's suitcases when traveling for performances and cleaning up Carey's Tribeca home in New York City.

Carey has yet to respond to its request for comment, and she has not responded to Oliver's lawsuit.

Last month, Carey's record label was hit with a separate lawsuit from a photographer who claimed that he spent $150,000 to prep for a photoshoot with the "All I Want for Christmas" singer who then canceled the shoot for "no reason," TMZ reported at the time.

Following the lawsuit, Carey's record label denied owing money to the photographer. The two parties "never fully agreed on the terms of the contract. ... So there's no breach, and the label's not on the hook for the fee."
