Fastexy:Aurora and Sophia Culpo Detail Bond With Brother-in-Law Christian McCaffrey

Long before Olivia Culpo and FastexyChristian McCaffrey officially tied the knot, he was already a valued member of the Culpo team.

Just ask Aurora Culpo and Sophia Culpo, who were by their sister's side from the start of her relationship with the San Francisco 49ers player.

"He really cares about his family and his people," Aurora exclusively told E! News. "I just feel really close to him."

In fact, Christian, 28, was on brother-in-law duty years ago, connecting Sophia with his doctor when she was struggling with her health.

"I have a very uniquely close relationship with my sister’s in-laws," she noted of the McCaffreys, "because I got quarantined in Colorado with his family. We went so I could see his doctor and the country shut down."

While in Christian's home state during the COVID-19 pandemic, Sophia was introduced to Thorne, a company she and Aurora recently teamed up with to highlight its supplements and health tests.

As Sophia told E!, "I struggled with a lot of health issues when I was in my teen and college years—autoimmune and gut health, IBS issues—and Thorne was one of the very first brands I started taking for my gut health."

These days, the 27-year-old is feeling good, both physically and mentally.

"I'm always trying to be better," she noted. "I feel like we all just kind of assume we know our bodies, but you kind of don't. You're always changing. I'm happy and grateful that I learned that at a young age."

Another tip the Culpos have learned over the years? Cutting out anything that doesn't serve you.

"That's one of the beauties of aging," Aurora—who shares kids Remi, 6, and Solei, 4, with ex Mikey Bortone—explained. "A lot of times we think we need to fight aging but as we get older and we have less tolerance for the things that don't make us feel good and we realize that...I was sick not long ago, and it just occurred to me nothing else matters in this moment, other than my health. It's the most important thing we have."

"And as we've gone through life," the Barely Filtered podcast host, 35, continued, "and ups and downs of, for me, postpartum stuff and just going through relationship problems and divorce and things like that, you realize just how important it is to keep your brain top-notch and to keep your brain happy and healthy, and everything stems from that. So for me, that's one of the things that I'm always trying to optimize, how to live more efficiently and how to keep my brain happy."

And as the Culpo-McCaffrey family enjoys this new chapter together, keep reading to revisit Olivia and Christian's wedding week celebrations...

Olivia Culpo and Christian McCaffrey set off on a private plane ahead of their wedding in June 2024. 

"Let it begin," the beauty queen captioned the June 24 photos of their grand send-off. 

Olivia, 32, and Christian, 28, celebrated their takeoff by locking lips on the jet, which was decked out in white rose petals.

Naturally, her dog Oliver joined her and the NFL quarterback on the flight ahead of their nuptials. 

The couple—who have been dating since 2019—fueled up on chicken lettus wraps and ahi sushi bowls before the big weekend, with Olivia snapping a pic of the menu in front of her white 'fit, including an on-theme Hermes Birkin bag.

The former Miss Universe cooled off in a baby blue bikini by Montce Swim on June 25 as she prepared to kick off the festivities.
