Serena Williams Shares First-Ever Pic of Daughter Olympia Holding Newborn Sister on IG

After Serena Williams, 41, and her husband, Alexis Ohanian, 40, welcomed their second baby girl into the world, the tennis star surprised her IG followers with a sweet photo of her oldest daughter, Alexis Olympia Ohanian Jr., spending some quality time with her little sister.

In a new photo shared on Olympia’s Instagram account, the 5-year-old is smiling from ear to ear as she holds her baby sister (who has her eyes closed) in her arms. While lying down in Olympia’s lap, her newborn sister (Adira River Ohanian) is wrapped up in a white baby blanket with blue and pink stripes.

The caption read, “My sister and me.”

Olympia’s followers flooded the comments section with heartwarming responses, with one person writing, “So sweet!” Another said, “Too cuteeeee.” And of course, Williams took a moment to gush over her two fave girls, commenting, “My babies.” Proud dad Alexis also chimed in and wrote, “The best big sis on the planet!”

This sister moment was shared just hours after the Grand Slam champ announced that she had given birth to her second child. In an Instagram post yesterday, Williams shared a photo of the new family of four. “Welcome, Adira River Ohanian,” she wrote in the caption.

“I’m grateful to report our house is teaming with love: a happy & healthy newborn girl and happy & healthy mama,” Williams continued. “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 [prayer emoji] I'll never forget the moment I introduced @olympiaohanian to her baby sister.”

We’re so excited to see more sister moments like this one.
