June 27 (UPI) -- Serena Williams recently went nude for the August issue of Vanity Fair.
The pregnant 35-year-old tennis pro stripped down for famed photographer Annie Leibovitz after announcing she's expecting her first child with fiancé Alexis Ohanian.
"Must read article," she captioned a photo of the magazine cover Tuesday for her 6 million Instagram followers.
Williams was "a little more than six months pregnant" when she spoke to Vanity Fair about her relationship with Ohanian, the co-founder of Reddit, and her impending motherhood. She confessed in the interview that her pregnancy "just doesn't seem real."
"If you would have told me last year in October or November that I would have a baby, not be pregnant but have a baby, I would have thought you were the biggest liar in the world," the star said. "This is kind of how I am right now. This is happening sooner than later, and it's going by so fast."
"I don't know what to do with a baby. I have nothing ... I've done absolutely nothing for the baby room," she later admitted.
Williams confirmed her pregnancy in April after getting engaged to Ohanian in December. She told Vogue at the 2017 Met gala in May that she and Ohanian are keeping their unborn child's sex a "surprise."
"We are waiting," the tennis pro said. "We call it 'baby.'"
