Not only that, she was pregnant when she won the Australian Open in January. In fact, during the whole tournament, she never dropped a set. Think about that for a minute. The tennis great announced it on Snapchat Wednesday and an equally thrilled dad -- Serena's fiance Alexis Ohanian -- confirmed it.

Serena and her Reddit co-founder fiance, 33, announced their engagement in December.

No word yet on the reaction of her famous big sister, Venus.
