“Meet Alexis Olympia Ohanian Jr.,” Williams captioned the mother-daughter moments along with the first photo and name reveal.

“It’s been a long time, but we had a lot of complications, but look who we got — we got a baby girl!” the tennis icon said in the video.

PEOPLE confirmed Williams’ pregnancy in April after she inadvertently revealed on Snapchat that she was 20-weeks along. Williams and Ohanian, 34, were engaged in December.
