The 23-time Grand Slam champion and her husband, Alexis Ohanian, are expecting a boy, the couple announced in a YouTube video.

The couple found out in quite a spectacular way as drones spelled out “It’s a…” as the guests waited patiently to see the gender. Then the drones spelled out “Boy.”

Williams’s daughter, five-year-old Olympia, was just as excited as her parents when the news became official. The video of Williams and Ohanian telling Olympia she was going to be an older sister went viral back in May as she was extremely excited to have a sibling.

Williams “evolved away” from tennis after last September’s U.S. Open. One of the biggest reasons behind her decision was the desire for the couple to grow their family. Williams previously won the 2017 Australian Open while pregnant with Olympia.
