While Supreme is outgoing and fun-loving in his personal life, he is conservative in business. "I'm careful about the films I appear in," Castro says. "I want to be represented in a positive manner and I want to look good, too!" He changed his name from Castro to Supreme when he started working with Pitbull Productions in New York City. "My brother came up with my new stage name. I wanted a name that reflects who I have become." He plays basketball and football, loves guns and expensive cars, and would love to own a one day.
