Serena Williams Strip Naked for America's ESPN Magazine Cover

Serena Williams certainly served up a surprise on the cover of America's ESPN magazine.The tennis champion peeled off her usual sportswear to appear completely naked on the cover of the publication's 'Body Issue'.The 28-year-old looks a picture of confidence while wearing nothing but a smile, her modesty saved only by some very strategic posing.

But the athlete has previously admitted she struggles to accept her body shape. 'My thighs... I think they're too big,' she has said. 'And also my arms. I think they're too muscular. They're too thick.'Sometimes I look at myself in the mirror and am, like, I want to lose my inner thigh. I've got to do an hour of cardio today, or whatever. I try not to do it, but the insecurity comes back sometimes.

'I want women to know that it's okay. You can be whatever size you are, and you can be beautiful both inside and out.'The release of the magazine in the US marks a triumphant day for Serena.She is now back on top of the rankings after a 6-3, 6-2 victory over Ekaterina Makarova in the second round of the China Open in Beijing.But her journey back to glory has not been without controversy - last month she made a furious outburst against a line judge at the US Open.
