Mowry, 42, said that because of that experience, she makes sure to always assure her children, Cree, 9, and Cairo, 1, of their worth. The idea that they would ever feel devalued is too painful a thought for her to bear. She also wishes she'd handled her situation differently.

"I wish I would've said something then," she said. "I wish I would've had the courage to speak out and say that that wasn't right."
