Serena Williams is making a different kind of racket.

A rap track recorded by the tennis champ leaked on Friday, finding the athlete dropping lines like "I ball hard/no tennis racket/I can see these haters through my Gucci glasses" and "Swag out this world/you should call me Venus," a reference to her star sister.

According to TMZ, she laid down several tracks at the B Major Music Group studios in Florida last year, a venue owned by Baltimore Ravens offensive tackle Bryant McKinnie.
