“Welcome Emmeline Grace. Evie is beyond happy to have a little sister and we are over the moon. We love you so much little Emmy.”

Stosur has been in a relationship with Liz Astling, who gave birth to Evie five years ago, since 2016. This time around the former world No.4 carried the child.

The Queenslander retired from tennis after the 2023 Australian Open, following a mixed doubles loss alongside countryman Matt Ebden. She had retired from singles the previous year after a career which netted more than US$21 million in prizemoney.

Stosur’s straight-sets US Open final win over Serena Williams came the year after her maiden grand slam decider at the French Open, which she lost to Francesca Schiavone.
