“I'm looking forward to marrying my best friend,” she said. “I'm very excited for that next chapter, and I feel very lucky. He's a great guy.”

As the wedding draws closer, Culpo revealed that she’s been experimenting with some new beauty treatments and adding in new things in order to prep her skin to look radiant for the big event.

“One of the things that I did recently with Dr. Ellie is this, it's called the Salmon sperm facial,” she said. “That was really interesting. Also, Dr. Diamond has this, I think it's called the Inst Facial. It's something. It's PRP with exosomes, and that's something that I had never tried before. That was really, really cool.”

The former Miss Universe also went on to say that so far “everything” with the wedding planning has been “so exciting,” and while there isn’t anything particularly “stressful” about it, a lot of planning was necessary to ensure “everybody’s happy.”

“It's just logistically complicated,” the model explained. “Figuring out what everyone's going to wear, figuring out, figuring out where everyone's going to stay, making sure that everybody's happy.”

“I feel like as a people pleaser, I want to make sure that everybody else is having the best time ever, but I know that everything will fall into place,” she added. “I feel really good about it.”

In March, Culpo gave her Instagram followers a sneak peak at some wedding details, including the potential role the couple’s toy goldendoodle, Oliver Sprinkles Culpo McCaffrey, would play  in the nuptials.

“I really want him to be the ring bearer,” she wrote alongside a picture of the pup, who has his very own Instagram account. “tbd lol.”

She also shared that her wedding gown is still in the works, writing, “I don't physically have the dress but I've been designing for months. I can't wait for the finished product!!”
