New York: Tennis superstar Serena Williams is pregnant and expecting to deliver her first baby this fall, her spokeswoman said on Wednesday.
Confirmation of Williams' pregnancy, in a statement from publicist Kelly Bush Novak, came hours after the 35-year-old athlete posted a photo of herself in a yellow one-piece bathing suit on the social media site Snapchat with the caption "20 weeks."
Williams was approximately two months pregnant when she captured her record 23rd Grand Slam tournament title at the Australian Open in January.
Her victory over older sister Venus Williams broke a tie with Steffi Graf for the most Grand Slam singles championships in the sport's modern era. Serena Williams has not played since, citing a knee injury.
Fans and celebrities reacted with a mixture of awe and glee to Williams' Snapchat post.
"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," wrote Twitter user
