Serena Williams shared the very first picture and video of her new baby girl on social media. 

The pint-sized bundle of joy is named after her father, Alexis Ohanian, and she's a junior. Her name is Alexis Olympia Ohanian, Jr. When she came into the world on Sept. 1, Alexis Jr. weighed 6 lbs and 14 ounces. But, she's had a larger-than-life impact on her proud parents from the second they met her.

"Meet Alexis Olympia Ohanian Jr. You have to check out link in bio for her amazing journey. Also check out my IG stories 😍😍❤️❤️" Williams captioned a picture of her baby on Instagram. You can take a look at the cute photo below.  

The tennis superstar also posted a video of her pregnancy journey with her fiancé who was always close by. This footage is on her website, SerenaWilliams.com, and YouTube. At the end of the vid, Williams revealed that her baby's birth involved some complications.

"We're leaving the hospital after six or seven days... We had a lot of complications. But, look at what we got! We got a baby girl." Take a look at the video below. 

Congrats, Serena and Alexis Sr.!
