Nick Cannon and Mariah Carey have seen their fair share of legal drama, considering they're going through a divorce. But now, they'll be entering a new courtroom battle because a former nanny is suing them.

According TMZ, Sionette DaCosta started caring for the famous couple's kids in October of 2013, when they were still babies. Right away she established a good relationship with the infants, she claims. Apparently, that didn't sit too well with the R&B superstar because she states DaCosta was overstepping her boundaries with the children. As a result, she was eventually fired.

Now, the former nanny, who made between $6,000 and $7,200 a month, is looking for back pay because she claims she was wrongfully terminated. She also alleges she was forced to work overtime with no pay, sometimes working 100 extra hours a week.

As the Daily News reports, DaCosta filed court documents in Manhattan Federal Court, in which she states she was never properly compensated.

"As such, she attended to their needs, not only at home, but also during Ms. Carey's travels for her global concerts and appearances," reads the suit. "Plaintiff was always behind the scenes and often by Ms. Carey's side."

The ex-nanny reveals that Carey would phone her at all hours of the night. "Plaintiff was on duty during all hours of each 24 hour day with no entitlement for breaks, for meals, and even for sleep," reads the court docs.

"Indeed, Ms. Carey would often call plaintiff at hours in the middle of the night, and demand to be taken to her children or to be updated on the status of her children... Ms. Carey would not tolerate any delay when she called, and plaintiff had to attend to her every demand, spontaneous or otherwise."

At this time, neither Nick nor his ex-wife have made any statements about the lawsuit.
