Williams' rep, who confirmed her pregnancy to ET, told Reuters that she will not be competing for the rest of the 2017 season as she prepares for her little one to arrive in the fall. The pregnant athlete will miss the French Open, Wimbledon and U.S. Open, but plans to return to tennis in 2018.
Williams surprised fans with her pregnancy announcement on Wednesday morning, as she took to Snapchat to share a photo of her burgeoning baby bump in a chic yellow swimsuit.
"20 weeks," she captioned the pic.
While Williams may be taking a break from tennis, her unborn baby has already gotten a taste of the sport, as the 23-time Grand Slam champion was approximately two months pregnant when she won the Australian Open singles title in January.
