Tennis superstar Serena Williams has picked up a microphone. The athlete/businesswoman/fashionista has now added 'emcee' to her lengthy list of activities. An untitled track hit the Web today (May 11th) and features the champion rhyming. "I ball hard no tennis racket/I can't see these haters through my Gucci glasses/I make hits like batting practice--they be like Serena, is you really rapping?" she rhymes over the track. Wow. So that's how it works? After dating Drake and Common, S-Will had to go hard in the studio?
