Can the iconic star of films like The Outsiders, The Karate Kid, and My Cousin Vinny handle the pressure on the dance floor? With Karina's help, absolutely! Best known for his movie roles, Ralph also has numerous TV credits including roles on hit shows like Entourage, Ugly Betty, and Psych. And like Karina, Ralph has also starred on Broadway.
