Just Serena Williams playing tennis in a belly shirt and stilettos on a street in Manhattan

Yesterday we saw Serena Williams singing karaoke in Times Square. Today we get to see her playing tennis in a belly shirt and stilettos against David Letterman on West 53rd Street in Manhattan.

I suppose this is a good way to warm up for the U.S. Open. If you can play tennis in those shoes on a street in Manhattan without breaking an ankle you’re probably ready to face down Maria Sharapova and friends at the Billie Jean King National Tennis Center.
