Serena Williams and Alexis Ohanian’s 5-year-old daughter Olympia must have been shocked if she stayed up to watch her parents at the Met Gala on Monday night. Mainly because the 23-time Grand Slam champion didn’t fill her in that she was pregnant with baby number 2 until after she shared the news with the world!

In a new video posted to Instagram today, Williams reveals the totally-toddler reason she kept the big news a secret, and honestly, it’s so relatable.

“Olympia does not know right now that I am pregnant,” Williams says in the video. “So the big reveal will be at the Met, and then before we leave, I’ll tell Olympia.”

Sounds like a decent plan, right? Williams then breaks down exactly why she chose to do it this way.

“The reason I haven’t told her is ‘cause, she can’t keep a secret,” Williams explains.

Ha! Can you imagine? The second I told my then-4-year-old about my pregnancy with his baby brother, he told the world — family, teachers, people at the grocery store. They are just so proud and excited to get a little sibling, they can’t help it! So if you don’t want everyone you know — or, literally, the whole world in Williams’ case — to know about your pregnancy, then you cannot tell a toddler.

Anyone who knows toddlers thought this was a fablous idea.

Ashley Graham commented, “Love love love this!”

“Ohhhhh I love the suspense!!!” one person wrote, adding, “Also… all of us are Olympia. You can’t tell us NOTHINNNNNN! We wouldn’t have held it. Lol!!”

“Not she can’t keep a secret😂😂😂,” another person said.

Someone else wrote, “Olympia would’ve spilled the tea 😂🤣.”

“Toddlers do NOT know how to keep secrets foreal😂😂.”

Williams video was also posted on her new YouTube channel, which you can surbscribe to for even more behnd-the-scenes moments of the growing family (and hopefully we’ll get Olympia’s full reaction, soon!).

Olympia will be excited, though, because she’s been praying for a sibling.

In an essay written for Vogue in Aug. 2022, Williams says that Olympia can’t wait to be a big sister. “Olympia says this a lot, even when she knows I’m listening,” she wrote. “Sometimes before bed, she prays to Jehovah to bring her a baby sister. (She doesn’t want anything to do with a boy!)”

Williams continued, “I’m the youngest of five sisters myself, and my sisters are my heroes, so this has felt like a moment I need to listen very carefully to.”
