Serena Williams may have lost in the semifinals of the US Open but she’s still buzzing on the Internets. An old video of her twerking to Lil Wayne’s “Got Money” started circulating the Internet again and after viewing it I can see why. The video shows the tennis star bent over and twerking in a short skirt with what looks like nothing under (granted the video is a little grainy), but her famous behind is on full display.
