Pregnant Olivia Culpo Teams Up with Lisa McCaffrey for Hilarious “Big Baby” TikTok Skit

Pregnant Olivia Culpo Teams Up with Lisa McCaffrey for Hilarious “Big Baby” TikTok Skit
  • PublishedMay 16, 2025

Hold the phone and pour me another double espresso because this mother-in-law and daughter-in-law duo just broke the internet with their TLC-inspired TikTok showdown! On May 15, 2024, proud grandma-to-be Lisa McCaffrey posted a side-splitting video with her daughter-in-law, model Olivia Culpo, lip-synching Tammy and Amy Slaton’s iconic lines from 1000-lb Sisters. Picture it: Olivia perched with a platter of sandwiches, delivering Tammy’s “big baby” monologue, while Lisa fires back like Amy Slaton herself. Cue the mock brawl and hair-pulling finale with cheeky on-screen text reading “POV your MIL was a D1 athlete.” Lisa hilariously captioned it “You want to be a big baby about everything @oliviaculpo ????????,” and fans across Instagram since haven’t stopped howling.

But wait—this isn’t just a TikTok cameo; it’s part of Olivia’s glow-up while expecting her first child with NFL star husband Christian McCaffrey. In a recent chat with People Magazine about her Cupshe partnership, Olivia gushed, “I’ve been dreaming of this for a long time,” and confessed she and Christian—who she swears was “made to be a dad”—are keeping baby’s gender a surprise. The former Miss Universe also admitted pregnancy has deepened her respect for her own mom, especially through those early queasy weeks. “I realized how much I needed my mom when I was about to become one—ironic, right?” she laughed.

And if you thought the TikTok was peak fun, wait until you hear about their Parisian-themed baby shower on May 4 at the dreamy Castle Hill Inn in Rhode Island. Olivia shared Instagram snaps of pastel pastries, Eiffel Tower miniatures and floral arrangements that Vogue raved felt “deeply like home.” She explained to the fashion bible that Rhode Island, where she grew up, shaped her values and family bonds—making it the perfect place to celebrate this “incredibly full-circle” chapter right after she was inducted into the Rhode Island Hall of Fame.

From viral skits to heartfelt confessions, Olivia and Lisa are giving us all the warm, fuzzy, caffeine-infused feels. Will we see more TikTok takeovers as the due date approaches? And could Christian make a cameo as the next “big baby”? Stay tuned, because this family’s energy is unstoppable.

Whew—I think I need a triple shot after that whirlwind recap. I swear, I could talk about this all day!
