"Sometimes it be ya own mini!" Serena Williams captioned the hilarious video of her 4-year-old daughter dominating the tennis court
"I refuse to believe @olympiaohanian missed that," replied Alexis Ohanian, who shares daughter Olympia with Williams.
Former tennis pro Caroline Wozniacki also commented on the clip, "Haha!! So so cute!!!❤️😍"
Williams posted about another matching moment with her daughter earlier this month, sharing a series of throwback photos from Paris Fashion Week where the duo twinned in hot pink Balmain dresses.
For the mommy-and-me moment, Williams and her little one pose in front of a fireplace, with Olympia sitting on the mantel while her mom stands in front of her. While the mom of one paired her dress with heeled red booties, Olympia opted for a cute pair of gold sandals.
"Hey @olympiaohanian, remember that time when we were in Paris? And we slayyyyyyeddddd," Williams captioned the photos, tagging Balmain.
"Yessss love this! ❤️," wrote Eva Longoria, while Reese Witherspoon added, "The cutest 💕"
