The full video, which you can watch above, gives a tour of the stunning nursery. The red-and-white-themed space includes floral decals on the walls, plush hot air balloons hanging from the ceiling and more. Meanwhile, we also get a cameo from Williams's other daughter, Alexis Olympia Ohanian Jr., 5, in the clip.
Williams and her husband, Reddit co-founder Alexis Ohanian, 40, have been married since November 2017. They welcomed Olympia in September of that same year.
The pair announced that they were expecting another kid at the Met Gala earlier this year. Prior to walking the red carpet (and flaunting her baby bump), Williams shared a post to Instagram that saw her and Ohanian posing together. However, the caption was what spilled the beans. “Was so excited when Anna Wintour invited the 3 of us to the Met Gala,” Williams cheekily wrote. Then, the tennis champ announced Adira's arrival with a post on August 22—a slideshow offering followers their first glimpse of the newborn.
