Tennis superstar and decorated athlete Serena Williams along with her husband Alexis Ohanian shared on social media that they welcomed their newest bundle of joy. Adira River Ohanian, the couple's second daughter, entered the world, and they couldn't be more thrilled. In the Instagram post, Williams, her husband and first daughter, Olympia, posed with the family's new addition.

"I'm grateful to report our house is teaming with love: a happy & healthy newborn girl and happy & healthy mama," Ohanian wrote. "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."

Williams officially announced her second pregnancy during the 2023 MetGala, where she proudly cupped her growing belly on the red carpet.

"Mama (@serenawilliams) & Papa love this parenting-thing, so we're back at it. @olympiaohanian is gonna be the best Big Sister—she's been asking & praying for this for a minute," Ohanian shared back in May.

The pro athlete and entrepreneur, was very candid about her struggles during her initial journey into motherhood. Experiencing several medical emergencies—including a life-threatening one—and other health-related issues, she spoke about her experience during her HBO documentary, "Being Serena."

“One minute, everything’s going according to plan, and then I’m being wheeled off for surgery. I was terrified. It was a whole new kind of fear,” she says in the documentary. “I can’t believe how much went wrong on my way to meeting her. I almost died. … But now, she’s the reason why this all means even more than it did before.”

While she hasn't shared details around this newest birth journey, it is refreshing to hear that she and baby Adira are healthy. As we congratulate and celebrate Serena Williams, we wanted to look back at some of her cutest mommy moments to-date with daughter Olympia.
