Kate Middleton is a self-proclaimed tennis fan [1], and it certainly showed during her latest appearance in London. On Tuesday, the royal, who is currently pregnant with her third child [2], served up some serious fun as she visited the Lawn Tennis Association at the National Tennis Center. Sporting a fashionable black tracksuit and sneakers [3], Kate couldn't contain her laughter as she tossed the ball around with some kids on the court. She even gave one boy a congratulatory high five after their one-on-one. Once again, she has proven that she's not too "princessy" to play sports [4], and we love it.
