Tennis star Serena Williams indicated she's pregnant in a post on Snapchat, but she deleted the Snapchat a few minutes after it was posted. A spokeswoman later confirmed that Williams is pregnant and expecting a child in the fall.

Williams, 35, got engaged to Reddit co-founder Alexis Ohanian in December.

Williams posted a photo on Snapchat on Wednesday morning with the caption "20 weeks."

Williams has won more Grand Slam titles than any other player in the Open Era, earning her 23rd at the Australian Open in January. The spokeswoman also confirmed that Williams will not play again in 2017.

In early March, she pulled out of Indian Wells and Miami, citing a knee injury. Her last competitive match was the Australian Open final, a 6-4, 6-4 victory over her sister Venus.
