An array of tennis stars have shown off their beach-ready bodies this summer, whether on land or on the water. Novak Djokovic enjoyed a bachelor party, Rafael Nadal and pals relished Ibiza, and Maria Sharapova and Grigor Dimitrov got caught in paparazzi lenses. Jelena Jankovic and Ana Ivanovic followed (swim)suit.

Now Serena Williams has joined the cast, potentially (if hardly subtly) dispelling the rumor that she's pregnant, a notion fanned by German tabloid rag Bild after her bizarre appearance in a second-round doubles match at Wimbledon.

Both vacationing and training in Croatia with hitting partner Sascha Bajin, Serena showed deft on-court strokes and a willingness to put herself out there publicly, from two-tone bikinis to candy-store shopping. (You can bet she did not enter a Sugarpova location.) Croatia may be Bajin's country of origin, but Serena is making herself right at home these days.
