Just when we thought the tennis star couldn't get any cooler (we first fell for her after reading these famous Serena Williams quotes and then again when Serena Williams got real about her body image), she revealed today that she's 20 weeks pregnant.
And, if you do the maths, it means that Serena was actually pregnant when she won the Australian Open back in January.
This is hugely exciting news for Serena considering that her and her Reddit co-founder fiancé are set to marry this year after Alexis Ohanian popped the question last December.
