Mariah Carey is a self-proclaimed diva, so it’s good to know that she embraces the fact that she can be a real piece of work to deal with. Mariah, who is known for her hit songs, including We Belong Together, literally calls the shots wherever she goes. If you ever considered working for this superstar, think again. Carey is known to treat her staff like her worst enemies, having admitted that she fires her nannies every time she senses that her children are becoming attached to them more than her. Mariah boasts of having had dozens of nannies since birthing her twins.
