Williams announced her pregnancy back in April when she accidentally posted a photo that said “22 weeks” on Snapchat. Before that, she and fiance Alexis Ohanian were engaged in December while they were on a romantic trip to Italy. The private couple hasn’t yet announced a wedding date or due date, but Williams has been keeping fans updated via her social media accounts.

Speculation as to the sex of their baby was swirling last week when Williams’s sister Venus referred to the baby as a “she.” Williams calmed excited fans and set the record straight by saying she doesn’t know whether her child will be a boy or a girl, as she wants it to be a surprise.
