In February, Williams opened up to CBS Mornings about stepping away from tennis and expanding her family. 

She said her daughter was eager to become a big sister.

"The other day she's like, 'Everyone has a brother or a sister but me.' And I'm like, 'Olympia, I'm working on it. Mommy worked a little too long in tennis, so it's takin' a little longer than expected,'" Williams recalled.
