The video is filmed by Adira’s 7-year-old sister, Olympia, and it features the 1-year-old helping her mom collect tennis balls on the court. But instead of returning one to the basket (per Williams’s request), she runs to the side and throws it at the fence. 

“Here, Adira. Put it here,” Williams says in the clip. “She was doing it. Now that we turned the camera [on], she doesn’t want to do it.” With a little education on keeping the ball in play, Adira will be tossing it over the net in no time. 

Williams wrote a caption that teased Adira’s future as a tennis superstar. “When’s too early? @adiraohanian,” she wrote.

In the comments section, followers couldn’t believe that Adira has grown so quickly. One person wrote, “Wait.. is this the baby she just had?” Another added, “How is she walking already?! You just had her.” 

Some fans noted the similarities between Adira, Olympia and Williams’s husband, Alexis Ohanian. One follower wrote, “So adorable and Serena you had the same baby twice lol.” Someone else commented, “Both girls stole their father’s face and their mother’s athleticism.”
