PRISON BREAK star Wentworth Miller has credited his success to pop diva Mariah Carey. The hunky TV actor was handpicked by Carey for her 2005 video We Belong Together - and Miller insists the exposure of the promo convinced producers to give him the lead in hit U.S. drama, Prison Break. He says, "Mariah's an international icon. The two days I spent working on her video did more for my career, gave me more exposure, than anything I'd done before Prison Break. I'm grateful for the opportunity."
