With all of the work Serena Williams is doing on court this week at Wimbledon, her 10-month-old daughter must have been inspired. Alexis Olympia Jr., who was born during the US Open, fittingly took her first steps during Wimbledon.

Of course, it's a devastating blow for the 36-year-old but her Twitter family was extremely supportive, and hopefully she feels a little better.

Serena was putting in work on the practice court ahead of her fourth-round match with fellow mom Evgeniya Rodina.
