Serena Williams is getting closer to welcoming her second child!

On Sunday (July 30), the star tennis athlete shared an exciting video on Instagram which highlighted what appears to be a gender reveal party.

“Big reveal coming soon to my YouTube channel. What do you think I’m having?”’, she captioned the post.

The compilation video shows scenes of the bash of the 23 Grand Slam champion, smiling and hugging party guests. Other moments feature her husband, Alexis Ohanian, and their 5-year-old daughter Olympia. In another frame, Williams is next to her father, Richard Williams, who is depicted in the 2021 Oscar-winning film King Richard.

For the fun party, Serena wore a cropped white t-shirt, a pink and white striped short mini skirt, and a double layer of pink and blue necklaces. She tied the look together with white sneakers.

The growing family had a sweet moment during the party while taking a picture in front of a balloon arch. Olympia is between her parents, holding a ribbon etched with “#1 Sister.” While Williams is by the pink side of the balloons holding a large blue and pink crayon in each hand. Ohanian is on the blue side of the arch.

The mom-to-be built up the suspense of her reveal during the video's last scene. The family can be seen looking at the sky as a colorful light display reads, “It’s A...”, as the words vanish.

Williams announced she was pregnant with her second child on the red carpet at the MET Gala alongside her husband in May.

During her pregnancy journey, she has taken fans along the ride with her during video diaries, highlighting the natural ingredients she uses to prevent stretch marks and how she stays fit while eating for two.
