After revealing that she was pregnant, Serena Williams unknowingly revealed another kinda-sorta secret after fans did the math…

The tennis legend won the Australian Open on January 28 of this year — that’s just 12 weeks ago.

Technically, Serena was 8 weeks pregnant at the time she won!

Holy mother of God! Now THAT is something to commend.

If her child doesn’t end up being a tennis warrior like their mom, we don’t know what we’re going to do with ourselves.

YAS, honey.

Serena Williams really won the Australian Open whilst pregnant…. I just. The domination is unreal, don’t even @ me. Greatest to EVER do it
