Serena Williams poses with the Daphne Akhurst Trophy after winning the women's singles final against Venus Williams at the 2017 Australian Open at Melbourne Park on Jan. 28, 2017 in Melbourne, Australia.

 

A spokeswoman for Serena Williams says the tennis star is pregnant.

Kelly Bush Novak wrote in an email to The Associated Press on Wednesday: "I'm happy to confirm Serena is expecting a baby this Fall."

Earlier in the day, Williams posted a photo of herself on the social media site Snapchat with the caption "20 weeks."

The 35-year-old Williams won her 23rd Grand Slam singles title at the Australian Open in January - a little less than 12 weeks ago - and has not competed since, citing a knee injury when withdrawing from tournaments at Indian Wells, California, and Key Biscayne, Florida.

She announced in late December that she was engaged to Reddit co-founder Alexis Ohanian.
