After months of rumors the two were romantically involved, Rihanna confirmed on April 8, 2010, that she and Kemp are a couple. "He's my boyfriend," she told Ryan Seacrest on his radio show. "It's new, and it's fun, and it's nothing too serious, you know. I don't want anything that's going to take up so much of my energy and time right now in a bad way. I just want to have fun, and that's what it's about."

The outfielder's nickname is "The Bison." It was bestowed on him during the second major league game of Kemp's career, when he stole second base during a game against the Atlanta Braves, prompting Braves' announcer Don Sutton said he looked "like a big buffalo running around the bases," because of his imposing size. "Buffalo" later turned into "The Bison."
