The 35-year-old reportedly gave birth to a baby girl at a hospital in Palm Beach, Florida, on Friday, September 1. Serena Williams and her boyfriend Alex Ohanian Williams accidentally announced her pregnancy in a Snapchat photo on April 19.
She posted a selfie that showed off her tiny baby bump, writing that she was “20 weeks” pregnant. Williams and 34-year-old Ohania got engaged in December 2016 and the pair have yet to announce a wedding date.
The tennis star played in two tournaments this season before going on sabbatical, including winning the Australian Open by defeating her sister, Venus Williams, in the final.
