TENNIS great Serena Williams is expecting her first child, revealing the news Wednesday with a teasing Snapchat post captioned “20 weeks.”

    Her spokesperson, Kelly Bush Novak, followed up with a statement confirming the pregnancy.

    “I’m happy to confirm Serena is expecting a baby this Fall,” she said, adding that while Williams won’t play again this year “she looks forward to returning in 2018.”

    Williams’ Snapchat post, quickly highlighted in U.S. media, showed the 35-year-old American in a yellow swimsuit with a baby bump.

    The timing means Williams was already expecting when she won her record-setting 23rd Grand Slam title at the Australian Open in January — where she beat her elder sister Venus in the final.

    “The GOAT herself @serenawilliams took to Snapchat to announce she’s 20 weeks pregnant! Congratulations Serena!” the U.S. Tennis Association, organizers of the U.S. Open, tweeted, using the acronym for “Greatest Of All Time.”

    For fans the announcement underscored Williams’ superwoman status.

    “Serena Williams was pregnant when she won her 23rd Grand Slam tournament at the Australian Open. And did not drop ONE SET. Let that sink in,” Twitter user @noelleharmony posted.

    In December, Williams announced her engagement to Reddit co-founder Alexis Ohanian, first sharing that news on the Reddit social media site.

    While pregnancy may spell the end of Williams’ season, it doesn’t mean she won’t be back on court.

    Belgium’s Kim Clijsters came out of retirement at the age of 26 after having a child and won three Grand Slam titles.

    Australians Evonne Goolagong and Margaret Court also won Grand Slam titles after having children.
