Serena Williams gives birth to second child, a daughter

Serena Williams is officially a mommy of two! The tennis legend and her husband, Alexis Ohanian, welcomed their second child—another girl—and shared the happy news on social media.

“Welcome, Adira River Ohanian,” he captioned a sweet family photo on Instagram. “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.”

The proud mama shared her news via TikTok in an adorable video, which she captioned “Welcome my beautiful angel.”

In a statement to PEOPLE over the summer, Ohanian revealed that big sister Olympia is extremely ready to be a big sister.

“No one’s more excited than her,” he said. “She’s been wanting this. She’s been praying and asking about this for quite some time, so she’s very ready.”

While Williams first revealed her baby bump on the Met Gala red carpet (such an iconic move), it was perhaps more memorable when she revealed her bump to her oldest daughter—who thought her mom was just getting “fat” before she was made aware that there was a tiny human sibling growing inside her.

“Olympia does not know right now that I am pregnant,” Serena shared in a May 23 YouTube video, “but she did call me fat and then she got really stressed out. She was like, ‘Mommy, you’re fat.’ I try not to take it personal ’cause I’m like super into fitness, but I’m like, ‘Um, am I?’”
