Olivia Culpo is officially in her mom era.

The former pageant queen announced on Instagram Sunday that she gave birth to her and husband Christian McCaffrey’s first baby, Colette.

The new mom shared a carousel of black-and-white images of their family of three in the hospital together.

In one photo, Culpo showed one of the infant’s arms and the side of her head as she lay on a fuzzy blanket. In another snap, the new parents and Colette posed together as the adorable baby covered her face with her hand.

Culpo and the NFL player have been an item since meeting in 2019.

The athlete proposed to his partner during a Utah vacation four years later.

Prior to the couple walking down the aisle in their June 2024 wedding, Culpo shared her fears about struggling to start a family due to her endometriosis.

“I worry all the time about my timeline,” she said on a 2022 “Culpo Sisters” episode. “I feel like I have to have kids ASAP.”

Nine months after her and McCaffrey’s Rhode Island nuptials, however, Culpo debuted her baby bump via Instagram.

“next chapter, motherhood,” the reality star captioned the March maternity shoot snaps.

Later that same month, Culpo explained to E! News why she had “always wanted” to wait to find out the sex of her upcoming arrival.

“Being healthy, that’s all you can ask for,” she said at the time. “I feel like I have a job and that’s to be as healthy and mindful as I possibly can.”

As for McCaffrey, she admitted that the San Francisco 49ers player was “back and forth” on holding out until birth.

“I think I will maybe convince him that it would be really fun to wait,” Culpo noted. “It would be such a nice surprise.”

The former Miss Universe did speculate about whether she had a baby boy or baby girl on the way in a subsequent TikTok breaking down “old wives tales.”

While many signs pointed to a daughter — including the model’s morning sickness and highly-positioned bump — the then-pregnant star’s “intuition” was leaning toward welcoming a son.

Culpo has been a proud aunt for many years to her brother Pete Culpo’s daughter, as well as sister Aurora Culpo’s two kids — son Remi and daughter Soleil.
