It's a girl!

Olivia Culpo and Christian McCaffrey are officially parents and the internet can't stop gushing.

The model and former Miss Universe, 33, announced the birth of her first child with the San Francisco 49ers running back on July 13. Their daughter, Colette Annalise McCaffrey, made her Instagram debut in a series of stunning black-and-white hospital photos posted over the weekend.

"Colette is so lucky to have the best daddy in the world. A love like no other," Culpo wrote on her Instagram Stories, while simply captioning the post with her daughter's full name. 

The celebratory post quickly sparked an outpouring of love from friends, celebrities, and fans alike. The official Miss Universe account commented, "Congratulations Queen 👑🤍," while close friend and fellow model Brooks Nader added, "AUNTIE BROOKSIE LOVES U SO MUCH COLETTE ❤️❤️❤️❤️."

Fans have been on baby watch since March, when Culpo first revealed her pregnancy with a series of glowing maternity photos, calling motherhood her "next chapter."

However, followers truly kicked the theory mill into overdrive over Fourth of July weekend, when she sparked a wave of speculation after jokingly saying "buns on the grill." This caption on Instagram lead some to believe she might be expecting twins.

"Wait…did Olivia Culpo just hint at twins??" one fan commented. "I swore she said buns, plural!"

Though only one little bun arrived, fans are already speculating about whether Culpo will continue to share her journey into motherhood or keep things more private. 

The baby's arrival also carries an emotional weight. Culpo has been candid about her struggles with endometriosis and her concerns around fertility. In a 2022 episode of The Culpo Sisters, she opened up about feeling pressured to start a family sooner rather than later. 

"There is so much that I don't know about what's going to happen in the future with that condition, and I worry all the time about my timeline," she said. "I feel like I have to have kids ASAP."

The couple, who often praised each other's support and connection in interviews, have shared glimpses of their pre-baby bonding rituals, including a two-person book club and twice-monthly date nights.

"You have to lean on each other," Olivia told E! News last spring. "Everything's better with another person that you can share experiences with."

With baby Colette's arrival, fans are waiting to see how their love story continues to unfold and whether Colette might be the newest star of the feed.
