The family shared sweet snaps on social media

Serena shared a snap of herself with baby Adira River Ohanian in her arms, with husband Alexis Ohanian and their first daughter at her side.

The star had announced her pregnancy in May in a cute Instagram post.

She today took to TikTok to share the new addition, with her husband also making a sweet post to reveal their bub’s name.

And that name has a very special meaning.

The name Adira means “strong, noble and powerful” – much like her mum.

Dad Alexis also said what the name meant to them.

He wrote on social media: “Welcome, 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. Serena Williams 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 Olympia Ohanian to her baby sister.

“Your peace would have been like a river, your well-being like the waves of the sea.”
