2008: R&B Duo: Rihanna & Chris Brown?
After adamantly denying being involved with actor Josh Hartnett, Rihanna is romantically linked to 18-year-old R&B star Chris Brown (pictured at Clive Davis' Pre-Grammy Party). "He's one of my closest friends in the industry," Rihanna tells Allure in January. "He makes me feel like a teenager. I have to act and think like an adult so much. He makes me feel young again." In February, the pair is spotted awfully close in a pool in Jamaica.
