Serena Williams looked flawless on set of the Late Show With David Letterman, wearing a black crop top that showed off her supremely sculpted abs and a tight skirt that accentuated her curves. The tennis pro is in New York ahead of the U.S. Open, where she will enter as the top seed in the competition and is the favorite to win. 

During the show, Serena taught Dave some new tennis moves and spoke about how it important it is for her to feel the energy of the crowd. The famed late night talk show host also snuck in a little flirting with the tennis ace, as they felt up on each other's abs. 

Check out the crazy footage and photos of Serena's insane curves in the above slide.
