Serena Williams of the USA celebrates a point over Maria Sharapova of Russia in her quarter final match during the Mutua Madrilena Madrid Open tennis tournament at the Caja Magica on May 11, 2012 in Madrid, Spain

*Serena Williams – currently competing at the Matua Madrilena Madrid Open in Spain – has apparently added hip hop to her list of extra curricular activities.

TMZ has unearthed and posted a clip of a track featuring the tennis star rapping.

According to the web site, she recorded a number of tracks last year in Florida. The one featured below, posted by TMZ, includes a reference to tennis within the first 30 seconds. She also gives a shout out to her fellow Grand Slam winning sister Venus Williams.

“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?”

The track uses a sample that seems to have been lifted from Daft Punk’s “Technologic” that Busta Rhymes used on his single “Touch It.”
