Matt Kemp on Rihanna: "She Makes Me Happy!"

Some folks have theorized it’s the L.A. lifestyle and girlfriend, singer Rihanna, who have impacted Matt Kemp’s baseball career for the worse.

“My girl has nothing to do with what I do on the baseball field,” Kemp says. “If anything she helps. She makes me happy, and as stressed as I am coming home sometimes, it’s nice to have someone there who just wants to support you.”
