Nick Cannon and Mariah Carey are reportedly being sued — as a former nanny claims she was fired for showing too much affection towards the couple’s kids, Monroe and Moroccan, 3.

In the lawsuit, Simonette DaCosta alleges she worked for the pair when the twins were infants, and claims she was in charge of feeding, bathing and comforting the kids. She says the Elusive Chanteuse allegedly “berated” her for showing too much affection — and insinuates Mariah was jealous the babies preferred the nanny to their own mother.
