Serena Williams Goes Topless for Sexy Spread in New SI Swimsuit Issue [PHOTOS]

Serena Williams is starring in SI's annual swimsuit issue. And while Kate Upton is this year's cover star, Serena gives everyone reason to pick up the magazine with her gorgeous spread.

Of course, Williams is already off to a great year. Just last month, she beat her sister Venus Williams to win her 23rd Grand Slam title.

“I felt like it was more just a celebration for everything we’ve done in sports, everything we’ve done for women, everything we’ve tried to do to inspire people,” Serena told ESPN. “This was my first Slam. My first big match against Venus was right here on this stadium court. I felt like everything had really come full circle.”

As far as the SI spread, it was shot in Turks & Caicos, and the 35 year-old poses sexily in the water, in a bikini, topless and more. Check out the photos below.
