Serena Williams and Alexis Ohanian's Daughter, Olympia, Is Officially a Big Sister

Serena Williams and Alexis Ohanian have together made two of the cutest kids: their daughters, Alexis Olympia and Adira River Ohanian. The couple, who got engaged in December 2016 and married in November 2017, treat Olympia like she's their whole world, and now she's sharing all the attention with her baby sister, who was born in August 2023.

Olympia was born in 2017. Between tennis serves and Nike campaigns, Williams spends as much time with her girl as humanly possible, and when Ohanian isn't helping to build tech empires, he's trying to figure out how to do his daughter's hair. In between that, the proud parents honor little Olympia's milestone moments, too.

In May 2022, Williams and Ohanian celebrated Olympia's first dance recital, with Ohanian sharing a snap of the couple happily posing with their daughter via an Instagram post. "First ballet recital for @olympiaohanian in the books 🙌 proud of you, Junior! (The ring pop was not part of the performance)," he captioned it. A few days before, Ohanian shared pictures from his father-daughter date at mini golf, writing, "I made the mistake of thinking my 4 year old would take mini-golf seriously (this footwear??), but it was still a great daddy-daughter date 🙌."

Williams and Ohanian's family is the sweetest, with Olympia's cute moments during family trips to London and Greece and her random Moana-themed party.

Now that their new addition has arrived, learn more about the Williams and Ohanian's kids ahead.

Alexis Olympia Ohanian Jr.

Alexis Jr., most commonly referred to by her middle name, Olympia, is Williams and Ohanian's first child together. She was born on Sept. 1, 2017, and quickly became the center of both Williams and Ohanian's lives. In fact, Williams previously told POPSUGAR that she plans on never leaving her daughter's side for even a day if she can help it.

"Yeah, absolutely, I feel great [about spending time away from her]. I feel like when she's 18, at college, it'll be hard for me, but I'll manage. Hopefully, she'll have a brother or a sister and they'll still be around." She added, laughing: "I'm so serious."

Turns out, Williams wasn't joking at all, because Olympia is now a big sister. On May 1, Ohanian shared photos of his and Williams's 2023 Met Gala looks on Instagram and captioned them, "Mama (@serenawilliams) & Papa love this parenting-thing, so we're back at it 😁 and @olympiaohanian is gonna be the best Big Sister—she's been asking & praying for this for a minute." In August, Williams and Ohanian welcomed another baby girl.

Adira River Ohanian

On Aug. 22, Williams and Ohanian announced the arrival of their second child, daughter Adira River Ohanian. "Welcome my beautiful angel," Williams captioned a TikTok video of her family of four.

Ohanian also celebrated the arrival of his daughter on Instagram, writing, "Welcome, Adira River Ohanian. I'm grateful to report our house is teaming with love: a happy & healthy newborn girl and happy & healthy mama. Feeling grateful. @serenawilliams you've now given me another incomparable gift — you're the GMOAT. Thanks to all the amazing medical staff who took care of my wife & our daughter 🙏 I'll never forget the moment I introduced @olympiaohanian to her baby sister."
