If you didn’t know Serena Williams is 20 weeks pregnant by her fiancé, Reddit co-founder Alexis Ohanian, now you know. The tennis champ showed off her bump on Snapchat wearing an itsy-bitsy, yellow one-piece that is surprisingly on-budget for us regular folk. 99 bucks? Yes, please!

Score her exact swimsuit on Lablancaswim.com before it sells out (because you know it’s bound to). The suit’s highlights are a plunging scoop neckline and gold side button details. Plus, the high-cut leg and low-cut back keep it sexy — even for the mama-to-be.
