Rihanna already dominates the pop charts, and with her new role in Battleship, the Barbadian singer is bringing her talents as a performer to a brand-new venue. We recently sat down with the actress at Pearl Harbor, where much of the action movie was shot, to talk about her debut as an actress. She talked about toughening up to fire some major weapons in her role as Petty Officer Raikes and why "everything" about making her first movie scared her. She also told us she could relate to the Navy officer's role as the lone woman in a sea of guys, which she said mirrors her "tomboy" childhood and the male-dominated music industry. Check out our interview and see Battleship in theaters starting May 18!
