| Celebrity Pregnancies

Tennis icon Serena Williams shocked fans when she revealed in a now-deleted Snapchat post last week that she was 20 weeks pregnant with her first child with fiancé Alexis Ohanian, and the athlete officially confirmed the news on Instagram Monday with a sweet message to her unborn child.

Williams used the social media platform to post a vacation selfie in which she sports a black bikini along with a visible bump, and the mom-to-be is pretty much glowing in the shot.
