Ocean's 8 might just be Rihanna's biggest movie yet. The pop singer took on the role of a hacker named Nine Ball and worked alongside Sarah Paulson, Sandra Bullock, Mindy Kaling, and Anne Hathaway. In fact, Paulson recently couldn't stop gushing about Rihanna. "She's this amazing performer and energy when you see her on stage or screen, but in person, she's — I would never use the word shy to describe her — but she has a reserved temperament on our set," she told Us Weekly. "She was more quiet. She's also so much fun and totally game for anything and excited to be there, but, very mellow."
