Williams first announced her pregnancy, albeit accidentally, with a Snapchat shared to her Story back in April, showing off her swimsuit-clad 20-month baby bump. She may have revealed her pregnancy by accident, but in the coming months, she continued to show off her changing body in a series of stunning maternity looks, including the custom emerald green Atelier Versace gown that she wore on the Met Gala red carpet (above).

And while she had to pull out of her upcoming tennis tournaments, she did find time to cheer on her big sister Venus Williams from the stands at the French Open. The 23-time Grand Slam winner even continued to hit the tennis court throughout her pregnancy, sharing a video of herself hitting some ferocious ground strokes.

Beyoncé took to Instagram Friday afternoon to congratulate the couple.

This tennis pro surely has another ace on her hands!
