Serena Williams announced on Snapchat on Wednesday that she is 20 weeks pregnant with her first child.
Jarett Wieselman of BuzzFeed News relayed a screenshot of Williams' post:
Williams has since removed the post, per Giri Nathan of Deadspin.
A representative for Williams confirmed the news to ESPN later in the day.
The 23-time Grand Slam champion and Reddit co-founder Alexis Ohanian got engaged in December 2016.
Williams, 35, started off her 2017 season in style when she broke Steffi Graf's Grand Slam record with a triumph over her sister, Venus, in the Australian Open final.
She has since been absent from WTA events, and if the 20-week timeline is accurate, it means she won the tournament while pregnant, per Janis Carr.
In March, Williams cited a knee injury as the reason for her withdrawal from the BNP Paribas Open in Indian Wells, California.
