This week, Serena Williams and husband Alexis Ohanian have a lot to celebrate. After sharing much of her pregnancy with fans along the way — including the gender reveal party the couple hosted earlier this summer — on Tuesday the couple announced the birth of their second child in a sweet TikTok video, letting their followers know their baby girl has finally arrived. Considering how the family has been vlogging their experience so far, it's no surprise they decided a video was right for this big moment, too.
Here are all the details we have about their brand-new little one so far.

Serena shared the exciting news in a TikTok video.
In the beginning of the video, Alexis is sitting with a laptop by himself, and then Serena comes to join him, followed by Olympia. At that point, Serena indicates she'll be right back … and returns with a brand-new baby in her arms.
"Welcome my beautiful angel," Serena captioned the video.
Alexis shared his daughter's name in an Instagram post.
Along with the first photo of their family of four, Alexis revealed that their new baby girl is named 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," he wrote.
He shared sweet photos of Adira and Olympia meeting for the first time.
Included in the post are photos of proud big sister Olympia holding her baby sis in her arms while sitting in a big chair in what looks like a hospital room, grinning from ear to ear.
"I'll never forget the moment I introduced @olympiaohanian to her baby sister," Alexis wrote.
We don't have any details about Adira's birth yet.
So far, the new parents of two haven't shared Adira's birthday or any of the specifics like that, but since they're typically open about their family, it wouldn't be surprising if more information (and more photos) was coming soon.
