Fresh from the Olympics, Serena Williams is gearing up for the U.S. Open, but that doesn't mean she isn't taking a little time off the court to get gussied up for a chat with David Letterman.

The tennis superstar was spotted outside of Letterman's "Late Show" wearing a skintight red dress that hugged her curves in all of the right places. She completed her look with a pair of killer 6-inch embellished Christian Louboutins -- the pricey pair reportedly set her back a cool $4,000. Now that's a style grand slam.

Check out Williams' strong and beautiful look below:
