Curvy tennis star Serena Williams gets her beach wiggle on... but her tiny bikini barely serves its purpose By Chris Johnson Last updated at 11:48 PM on 17th April 2011 Comments (63) Add to My Stories Serena Williams looks in great spirits as she confidently shimmies down the beach in a mis-matched bikini. The Wimbledon tennis champion put on a little dance as she relaxed with friends in Miami today. But the 29-year-old sports star came close to a double fault as she put on her active display - with her strapless bikini top clearly struggling to contain her ample bosom. Check me out: A confident Serena Williams relaxes with friends on the beach in Miami today and was spotted dancing around, appearing to be in a very cheerful mood Making a splash: The tennis star is recuperating at the moment following emergency surgery in February to have a blood clot removed from her lung Roll with it: Serena Williams busted some moves on the Miami beach Serena has been enjoying some recuperation time in Miami recently following emergency surgery two months ago. She is recovering from an operation to remove a blood clot 'the size of a grapefruit' found in her lung in February. Serena had developed a haematoma from a pulmonary embolism, stemming from an incident when she cut her foot on broken glass in a Munich restaurant last July. And she admitted to being very down of late, having being sidelined from her sport since claiming her 13th Grand Slam title at Wimbledon last July. 'I definitely have not been happy,' she said recently. 'Especially when I had that second (foot) surgery, I was definitely depressed. I cried all the time. I was miserable to be around.' Revealing: The sports star wore a mis-matched bikini, but her strapless top half appeared to struggle to contain her ample bosom Serena, who has slipped to world number 11 in her absence from the WTA Tour, is unlikely to return before the summer and admitted that the time spent on the sidelines had taken an emotional toll. A part of her lung had 'died' from the pulmonary embolism and she has remained on blood thinning medication. But while she hasn't been able to play tennis, Serena has been able to keep up with her lucrative sponsorship contracts. A TV advert featuring her curvy figure was recently released to promote Top Spin 4, a tennis game made for the Wii console. But it is unlikely to be seen by many - the games maker 2K Sports rejected it because it was deemed too raunchy.
