On Tuesday, it was announced that Williams will make her competitive comeback to tennis next January to defend her title at the Australian Open, the same tournament she beat her sister Venus in the final while pregnant.
”Serena will be back,” tournament director Craig Tiley said, according to Sports Illustrated, saying that Williams “is planning” on playing in the Jan. 15-28 competition.

Williams previously told Vanity Fair that she would return to competitive tennis in January 2018.
Days later, she declared her promise during the TED 2017 Conference in Vancouver, telling Gayle King, “I definitely plan on coming back. I’m not done yet. If [Venus is] still playing, I know I can play. This is just a new part of my life. My baby’s going to be in the stands and hopefully cheering for me.”
