Williams, 35, gave birth to a baby girl at a hospital in Palm Beach, Florida, on Friday, September 1, the source tells Us.
As previously reported, 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.
“On social media you press the wrong button and … 30 minutes later, I missed 4 calls and I’m like, 'That’s weird,'" she explained to Gayle King during a TED conference in Vancouver days later.
Following the announcement, Williams shared several more baby bump pictures on social media and opened up about becoming a mom. She also graced the August 2017 cover of Vanity Fair, stripping down to just a thong.
“I don’t know what to do with a baby,” she told the magazine. “I have nothing … I’ve done absolutely nothing for the baby room.”
The athlete learned that she was expecting shortly before winning the Australian Open in January. She was so shocked that she took six pregnancy tests. "[I] did a double take and my heart dropped," she told Vanity Fair. "Like literally, it dropped."
Williams and Ohanian, 34, got engaged in December 2016. The pair have yet to announce a wedding date.
