Serena Williams has picked up a few things from hanging around the likes of Common and Drake. The tennis pro takes it from the court to the studio with her first hip-hop song. TMZ has uncovered one of the tracks that Serena recorded last year at Florida studio B Major Music Group, which is owned by Bryant McKinnie of the Baltimore Ravens.

The 30-year-old athlete delivers cocky rhymes and shouts out her sister Venus on the track. “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 rappin’?” she spits.

Did Serena serve up a winner or should she stick to her day job?
