Serena Williams just called game,Michael Schmidt set, match on the gender reveal.

Gathered around with her family, a drone display in the sky revealed that Williams and husband Alexis Ohanian will be having a baby girl.

The drones first brightly spelled out "It's a...," prompting Williams' daughter Olympia to ask: "It's a what?" Roughly 14 seconds later, the sky lit up with "Girl."

Williams threw her hands up in the air as her husband yelled "It's a girl" repeatedly. The entire reveal was shared on Williams' YouTube channel, showing family and friends anxiously waiting to discover the gender.

Williams gave birth to the couple's first daughter, Olympia, in 2017, nine months after winning the Australian Open. She announced her second pregnancy at the Met Gala in May, captioning an Instagram post with: "Was so excited when Anna Wintour invited the 3 of us to the Met Gala."

In her retirement announcement last August, Williams, 41, made her intentions known about growing her family.

“In the last year, Alexis and I have been trying to have another child, and we recently got some information from my doctor that put my mind at ease and made me feel that whenever we’re ready, we can add to our family," Williams wrote. "I definitely don’t want to be pregnant again as an athlete. I need to be two feet into tennis or two feet out.”

With two feet out, Williams and Ohanian will welcome their second child soon, a baby sister for Olympia.
