Serena Williams broke the internet on Wednesday when she announced that she is expecting her first child with fiancé and Reddit founder Alexis Ohanian. As is fitting for the 23-time grand slam champ, Williams revealed her pregnancy news in a stunning fashion.

Williams showed off her growing baby bump in a one-piece swimsuit with the simple caption: “20 Weeks.”

Although she didn’t tag the brand of the suit in the Snap, eagle-eyed shoppers revealed that the 35-year-old is wearing the La Blanca Swim Anniversary Two-Button One-Piece ($99). The swimwear is still available online and in six colors, but sadly, the super flattering yellow one that Williams is wearing isn’t available. A La Blanca rep toldRefinery 29 that it was custom-made for her.
