Yes, yes, I know. Serena Williams has pulled out of next week’s Marbella tournament in Spain with the knee injury that’s sidelined her since the Australian Open. Yet she’s been spotted wearing “14 inches of heels”, as Marion Bartoli put it, while cheering Venus on at the Sony Ericsson Open, and now we see she’s caught frolicking in the ocean in an itty bitty bikini. So what? Just because you have a bum knee doesn’t mean you have to recuperate in a full body cast.

Here are some shots of Serena playing with friends on Friday in the Miami sun and surf. At least we know that she’s been keeping up with her fitness!

Here she is last week (March 25)  in an fashion-forward one piece. Doesn’t she look like she’s really enjoying her vacation? I’m jealous.

Per tennis.com, Serena Williams is out of the Marbella tournament (replaced by this weekend’s Miami champ, Kim Clijsters) and “questionable” for Rome, which starts on May 2nd. The Fed Cup is also up in the air – the US plays Russia in the semis in Birmingham, Alabama, the weekend of April 24th. So Serena could be benefiting (?) from more than a 3 month break before entering the Major season.

Huh. Anyone know what Dinara Safina’s been up to? Frolicking much?
