Tennis superstar Serena Wiliams is pregnant, with a spokeswoman confirming the news yesterday (April 19th) and saying she's due in the fall, hours after Williams posted a Snapchat photo of her body in profile with the caption, "20 weeks." That set off a frenzy of speculation, and Williams deleted the photo not long after. That timeline means that the 35-year-old Williams was pregnant when she won her record 23rd Grand Slam singles title at the Australian Open in January, just under 12 weeks ago. She hasn't competed since, blaming a knee injury. Williams announced in December that she was engaged to Reddit co-founder Alexis Ohanian.
