Congratulations came pouring in after former American tennis superstar Serena Wiliams and her husband, Alexis Ohanian, announced that they recently welcomed their daughter, Adira River Ohanian.

The couple made the big announcement through a series of social media posts on Tuesday, August 22.

Several fans took the opportunity to congratulate the tennis great on her new bundle of joy.

Her husband also used the opportunity to welcome his newborn and thanked the medical team who assisted his wife and daughter during childbirth.

“Welcome, Adira River Ohanian. I’m grateful to report our house is teaming with love: a happy and healthy newborn girl and happy and 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 and our daughter. I’ll never forget the moment I introduced @olympiahonian to her baby sister,” he said.

“You’re peace would have been like a river, your well-being like the waves of the sea,” Ohanian added.

The retired tennis player publicly announced her pregnancy in May, when she flaunted her baby bump at the Met Gala.
