Olivia Culpo is officially expanding her famous family, and her sister Sophia Culpo is celebrating in true younger sibling fashion.

Once Olivia announced that she and her husband Christian McCaffrey are expecting their first baby together, Sophia took to her Instagram Stories to playfully point out that her older sister wasn’t the best at hiding her baby bump.

“Now you all know why her nickname is Oblivia... she ain’t stealth 😂 😂 ,” the actor and social media star wrote alongside a festive pic of Christian and Olivia, who held her pup Oliver Sprinkles over her stomach.

Sophia playfully called out her sister in a series of screenshots on her Instagram Stories (yes, as a younger sibling, I can confirm it’s that serious). Aside from Oliver’s cameo, Sophia pointed out that Olivia wouldn’t conceal her baby bump and would say, “I’m just bloated.”

ICYMI, Olivia and the San Francisco 49ers running back have been romantically linked since 2019 and tied the knot during a gorgeous ceremony in the model’s home state, Rhode Island, in July 2024.

The couple announced that they are expecting their first baby together on Monday, March 10 with stunning and sweet social media posts. First, the former Miss Universe pageant winner posted two professionally shot black and white photographs of her grazing her baby bump in a flowy white gown.

“Next chapter, motherhood 🤍,” she captioned the pics, while Sophia commented, “Counting down the days!!!!!🥹🥹🥹.”

Then, Olivia and Christian dropped a joint Instagram Reel with behind-the-scenes content from their maternity shoot. They frolicked in a field with deer in the distance and exchanged kisses for the camera before posing with sonogram photos of their baby with “Bloom” by The Paper Kites as the soundtrack.
