Forget tennis, Serena Williams got a new sport ... the rap game -- and she's making her debut with a brand new song that's actually pretty catchy.
TMZ broke the story ... Serena laid down some tracks last year at a Florida record studio called B Major Music Group -- owned by Baltimore Ravens offensive tackle Bryant McKinnie, who's good friends with the Williams sisters.
Now, one of the tracks has finally surfaced -- and it ain't half bad.
The lyrics are a little cliché -- shocker, another song about "balling hard" -- but her flow is surprisingly not annoying. She even gives her sister Venus a little shoutout.
Take a listen. Or don't. It's Friday. Do what you want.
A CD came out of nowhere almost hitting Legendtina but she quickly moved. Her legendary senses were back. She saw no one around. Quickly picking up the CD she nearly vomited. It was an Ashanti greatest hits CD. But she knew the island was playing tricks on her because no such thing existed.
