The tennis champion shared a glimpse of their daughter, Alexis Olympia Ohanan, Jr. on Instagram, two weeks after her birth.
The award-winning athlete shared a photo of herself with her newborn daughter on her chest.
"Tennis star Serena Williams gives birth to baby girl weighing 6 pounds, 13 ounces".
She finished off the clip with a heartwarming bio for her little girl.
Her father wrote: "Welcome, Olympia, we're so happy to meet you". "It's been a long time, but we had a lot of complications, but look who we got - we got a baby girl".
Serena accidentally revealed she was pregnant after she made public a Snapchat that showed her tummy at 20 weeks.
And, amazingly, she's listed as having won one Grand Slam title, seeing as her mum was pregnant during the Australian Open.
The couple welcomed their first child together on September 1 at St Mary's Medical Centre in West Palm Beach, Florida.
