Serena Williams -- Double Faults At Dancing ... Is Still A Badass

Listen, we all love Serena Williams. We all know she's succeeded in almost everything she's done including fashion design, tennis, and modeling.

We said ALMOST.

Here's Serena dancing at what looks to be some type of hip-hop or interpretive dance class and the reality is ... she's a really great tennis player.

Looks like SW and Venus are due to hit up the class together next week so who knows ... maybe she's more of a doubles player when it comes to the art of the dance.
