Olivia Culpo says she couldn't work out or walk for the first four months of her pregnancy, saying that she's "really making it count now." The model is expecting her first baby with husband Christian McCaffrey.

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.”
