Olivia Culpo welcomes 2nd baby with husband Christian McCaffrey

Olivia Culpo and her husband Christian McCaffrey are now a family of four!

The 34-year-old model and actress took to her Instagram account on Saturday and announced in a joint post with her husband that they have welcomed their baby in September.

In the announcement post, the newly minted parent revealed that Olivia gave birth to a baby boy on September 29.

Revealing the little bundle of joy's name, she penned in the caption, "Roman Augustus McCaffrey" along with a white heart emoji.

The Next Gen Chef host and Christian also shared a black-and-white snap of Olivia after giving birth, cradling her newborn baby on a hospital bed.

The post also included several snaps of the couple and their eldest daughter, Colette, who is 14 months old.

In one of the slides, Colette, wearing a cute pink bow in her hair, can be seen peeking at her baby brother, while Olivia holds both of her kids on a bed.

One shot also showed Olivia and her husband posing for a selfie, apparently before giving birth.

The carousel concluded with a sweet photo of Olivia carrying Roman in a garden, with Colette standing beside her.

Olivia penned on her stories, “Heart is exploding,” as she reshared the post.

The pair first announced the second pregnancy news on Olivia’s 34th birthday in May.
