Ready for some serious sweetness? You might recall that Serena Williams and daughter Olympia wore matching pink swimsuits (opens in new tab) last month, Williams' reading "The Shady One" and Olympia's reading "Wild Child." Well, they've only gone and done it again—and stepped it up a level with the inclusion of Olympia's favorite doll (and social media star in her own right (opens in new tab)) Qai Qai.

Williams shared a truly adorable snap Tuesday of herself, Olympia, and Qai Qai standing by the pool, all wearing bright pink Nike swimsuits. "When @nike makes a swimsuit for not just @olympiaohanian but @realqaiqai too," she captioned the post. The cutest!

Williams and Olympia are no strangers to twinning, with the mom and daughter starring in a Stuart Weitzman campaign (opens in new tab) together that launched last month. Announcing the campaign on Instagram (opens in new tab), Williams shared a sweet tribute to her "mini-me," writing, "I love that it’s called #FootstepstoFollow because she inspires every step I take and I hope I inspire her, too. Because while I try to teach her how to be a positive influence, she in fact teaches me how to be a stronger person every day. It’s the best part about being a mom."

Olympia absolutely nailed it on the Stuart Weitzman set, Williams later revealed in an interview with WWD (opens in new tab). "We were getting nervous—she took her nap [before] and you can’t shoot with kids for that long, so she came and went nuts—just pose, pose, pose—and then she was out. I was like—that’s how you shoot," she recalled. A true professional!
