Well, I'll be! Miss Serena Williams doesn't just play tennis and wear short shorts, she raps too! The professional tennis champion hit up (Baltimore Ravens') Bryant Mckinnie's music studio to create a rap song--for fun!

Serena delivers such lines as "schooling these rappers; they should pay tuition." Alrighty then. As long as the tuition is affordable, we agree with Serena. She ain't half-bad, considering...

"They" should indeed bow down to your glory, Serena, on and off the court. Or wherever else you may feel is appropriate. Mmhmm...kay.
