The greatest tennis player of all time is pregnant.

Serena Williams announced that she's 20 weeks pregnant in a simple Snapchat post.

It will be the 35-year-old's first child. She and Reddit co-founder Alexis Ohanian got engaged in December.

Her pregnancy sent shockwaves across the internet — specifically because she and her good friend Beyoncé are pregnant at the same time.

Best of all, Williams' pregnancy announcement proves one thing: Her child is already a champion.

Williams won the Australian Open in January. Since Williams is 20 weeks along, it's clear that she won the Open — her 23 Grand Slam victory — while pregnant.

Of course, that realization wasn't lost on her fans.

Clearly, that means her child's fate is sealed.

And Williams' greatness is still unparalleled.

Congrats, champ!
