Many celebrities love giving their babies unique and unusual names. However, some still prefer to go a more traditional route, and one of the most traditional routes, of course, is to name a daughter after the mother and a son after the father.

However, far from traditional, Serena chose to give her baby a name that breaks gender norms in more ways than one.

The world champion took to Instagram to share her first picture of their newborn.

"Meet Alexis Olympia Ohanian Jr," she wrote in the caption.

The newborn is named Alexis, after her husband. And the girl doesn't just carry her father's name — she's also a Jr. That's a title you almost see exclusively on boys, and basically never when a girl is named after her father.

 For her middle name, the pair chose Olympia, which is obviously a nod to Serena's icon status and gold medals. This baby is going to be such a boss!

Serena urged viewers to visit the link in her bio. It goes to her website, where you get blessed with this gem...

The montage of videos taken throughout Serena's pregnancy will have you in tears. There's footage of Serena and Alexis excitedly visiting the doctor and practicing swaddling on their puppies, as well as Serena smiling in a Snapchat video at the Australian Open captioned, "No one knows I'm 8 weeks pregnant." 

Throughout the video, Alexis continuously praises her with lines like, "Your mother is the most beautiful woman on earth." SWOON.

At the end of the video, there's adorable footage of their newborn at the hospital as Serena tells the camera, “So we’re leaving the hospital after six, seven days. It’s been a long time, we had a lot of complications. But look who we got — we got a baby girl! Junior!" 

Fans on Twitter are obviously elated for the new family.

Our thoughts exactly!

Congrats to the happy couple!
