The Culpo clan just got bigger!

Aurora Culpo gave birth to a baby girl on May 15, sharing the news via Instagram on Friday.

“Our sweet Selene 🌙,” Culpo captioned sweet hospital snaps of her third child, her first with fiancé Zac. “5.15.26. We are so in love 🤍.”

She went on to describe her birth experience via Instagram Stories over the weekend, revealing, “I had a scheduled C-section at 39 weeks mostly by choice. … It wasn’t bad! Honestly, the worst part was getting an IV in.”

The “Culpo Sisters” alum is also the mother of son Remi and daughter Solei, whom she shares with ex-husband Michael “Mikey” Bortone.

The former couple separated in January 2022, with Culpo filing for divorce from her spouse three months later.

Their divorce was settled in August of the following year.

While it remains unclear when the reality star moved on with Zac, the duo made their romance Instagram-official in April 2025.

“If you had told me a few years ago that I’d have happy, well-adjusted kids, a peaceful co-parenting relationship, a job I genuinely love and a new relationship that feels grounded and hopeful … I would believe you,” Culpo told her followers at the time.

“Laguna Beach” alum Kristin Cavallari subsequently messaged Culpo and revealed she used to date Zac while in high school.

“He was in love with her. She dumped him, my poor boy,” the “Barely Filtered” podcast host revealed in a May 2025 episode.

In October 2025, Zac proposed to Culpo while on a trip to Paris.

The bride-to-be posted social media snaps of her partner down on one knee at the time, gushing, “Said YES in the city of love!! 🇫🇷❤️💍”

Cavallari, 39, commented, “OMGGGG!!!!! Congrats guys!!!!! ♥️♥️♥️”

Culpo debuted her baby bump in maternity shoot pics two months later, writing, “We’re so excited to meet you 🤍.”

The duo used a pink cake to announce via Instagram that they had a baby girl on the way.

Culpo praised Zac in February as her “rock and comic relief” while she “felt like an exposed nerve” navigating her pregnancy, raving that he “somehow … just loved [her] right through it.”

Aurora became an aunt in July 2025 when Olivia Culpo welcomed daughter Colette — and the former pageant queen announced earlier this month that she is expecting baby No. 2 with husband Christian McCaffrey.
