Earlier this month, Serena Williams surprised friends and fans when she debuted her baby bump on the Met Gala red carpet. But before revealing her pregnancy to the world, she had to share the news with her biggest fan—her daughter Olympia.

In a new video entitled Olympia’s Surprise, Williams intros her “big sister,” reveal sharing that her daughter doesn’t know she’s pregnant yet but has been stressed out about mommy “getting fat.” Joking that her 5-year-old can’t keep a secret, Williams waited until the last possible moment to spill the beans.

Sitting on a couch with her husband Alexis Ohanian and Olympia between them, Williams finally broke the news. “You know how you’ve been praying for a little sister or brother,” Williams said. “Well we went to the doctor, and it turns out I’m not getting fat, but I have a baby in my belly.”

“Are you kidding me,” Olympia excitedly responded, “No you’re going to be a big sister!” chimed in Ohanian. The big-sister-to-be quickly hugged Mom and, after a quick peek at her bump, excitedly ran around the room shouting, running into walls, jumping over the couch and giving her parents quite the laugh.

Serena Williams Announces She’s Pregnant with Baby No. 2

Just a little less than a year after announcing her retirement from tennis to focus on her family, the 41-year-old all-time tennis great announced she was expecting her second child with her husband Alexis Ohanian. Williams shared the news with fans on Instagram on May 1. “Was so excited when Anna Wintour invited the 3 of us to the Met Gala,” Williams captioned the photo featuring her and Ohanian in their Met Gala best.

Adorned in Tiffany & Co. pearls and wearing a custom Gucci gown, Williams proudly cradled her baby bump in other photos throughout the carousel of images. Friends and fans flooded the comments with their well wishes. Singer Ciara, actress Tabitha Brown and Black Panther actor Michael B. Jordan were just a few of the celebrities to send their congratulations.


Williams and Ohanian are already the proud parents of 5-year-old Olympia. The venture capitalist has opened up several times about her traumatic birth experience and difficult postpartum recovery over the past few years. In light of her first pregnancy difficulties, Williams made the decision to “evolve away from tennis” in August 2022. In the Vogue essay outlining her retirement, the professional athlete noted that she “definitely didn’t want to be pregnant again as an athlete. I need to be two feet into tennis or two feet out.”

While a difficult decision to leave her career in pursuit of motherhood, Williams noted that it feels like anything but a sacrifice. “The fact is that nothing is a sacrifice for me when it comes to Olympia. It all just makes sense. I want to teach her how to tie her shoes, how to read, where babies come from, and about God. Just like my mom taught me. As she grows, it’s something different every month,” Williams shared, adding, “I think tennis, by comparison, has always felt like a sacrifice—though it’s one I enjoyed making.”

Our congratulations to Williams on her growing family!
