Congrats Serena Williams!

The tennis star announced that she is pregnant with her first child! Williams posted a photo of her baby bump on Snap Chat. See the PHOTO HERE!

In the photo, the 35-year-old is wearing a yellow one-piece swimsuit, with the caption "20 weeks."

My only regret is not pointing my toe sorry coach Garry 🙈
