Olivia Culpo may have just sent the internet into a frenzy with one single word.

The former Miss Universe and model, 33, is currently expecting her first child with NFL star husband Christian McCaffrey, and fans are convinced she subtly revealed that more than one baby is on the way.

The theory? All thanks to a festive Fourth of July Instagram post.

“Buns in the oven, burgers on the grill ❤️🇺🇸 happy 4th love you all ❤️❤️❤️❤️,” she captioned a carousel of holiday photos, showing off her growing bump in a red bikini top and white pants while celebrating with McCaffrey, family, and friends.

But fans couldn’t help but zero in on the word “buns”– plural.

“Buns!? As in plural omg lol ❤️❤️❤️❤️” one follower asked, sparking a comment section full of speculation. “I think she is having twins," said another. "Buns as in plural babies? Or did you mean bun’s (bun is)?," shared a follower, trying to make sense of the caption. 

Whether the plural phrasing was intentional or just holiday wordplay, fans are eating it up. After all, the model and McCaffrey's pregnancy announcement back in March already had fans hooked and now, they’re more invested than ever.

Over the past few months, The Culpo Sisters star has shared heartfelt moments from her journey into motherhood, from black-and-white maternity shots to bump-baring fashion moments and behind-the-scenes glimpses into married life.

The couple, who tied the knot in a stunning Rhode Island ceremony in June 2024, have become fan favorites thanks to their sweet love story and low-key presence on social media.

And now, with her due date reportedly right around the corner, followers are practically refreshing their feeds on the hour, waiting for baby news. “Any day now,” one fan commented on her latest post. “We’re ready when you are, mama!”

While Culpo has been transparent about much of her pregnancy, longtime followers wouldn’t be shocked if she decided to keep certain details private, like whether there’s more than one baby on the way. After all, the couple has managed to keep some big moments under wraps before, including subtle signs of pregnancy before their public announcement.

Whether it’s one baby or two, fans are simply excited to see her step into motherhood. And if this latest post was, in fact, a quiet confirmation of twins? Well, it wouldn’t be the first time her followers cracked the code before the official reveal.
