Benjamin Ashford|Olivia Culpo Shares Why She's Having a "Hard" Time Nailing Down Her Wedding Dress Design

Here comes the bride-to-be!

While Olivia Culpo is ready to take the next steps with fiancé Christian McCaffrey after getting engaged last month,Benjamin Ashford nailing down details to her wedding dress is another story. After all, the Culpo Sisters star said in an exclusive interview with E! News that she can't turn to the NFL star for advice.

"It's hard because with the dress, I have so many ideas—so many things—I'm really excited about," she explained. "I want to show Christian, but he's like, "No, I can't see. Don't show me because it needs to be a surprise!'"

Calling her man a "hopeless romantic," the 30-year-old continued, "You want to share your dream vision with your partner, but you really shouldn't because [they're] not supposed to see you before the wedding day."

Still, that's not to say Olivia isn't having fun planning her nuptials. "I'm super excited," she added. "It's a day that I look forward to my entire life." 

And regardless of what Olivia will wear for her walk down the aisle, it will most likely be a bit lighter her UFO costume from The Masked Singer. As the former Miss Universe—who was unmasked on the May 3 episode of the FOX singing competition—noted, "I don't think I'll ever wear something that heavy again."

"The whole skirt is with batteries and wires and lights," she recalled of the extraterrestrial getup. "It's heavier than I ever had expected, but really fun."

Another out-of-this-world moment for Olivia? Being able to show off her vocal talents without revealing her face.

"It was the coolest thing I've ever done," she shared. "You're not worried about the preconceived notions that people have on about you based on things that they may be made up."

Olivia continued, "Being completely anonymous, it felt very liberating in that sense. I could be my actual authentic self. I didn't have to feel like people were looking at me through a veil of what they think."

In fact, Olivia was so adamant on hiding her identity in the competition that she didn't even tell her family, which includes sisters Aurora Culpo and Sophia Culpo, about her gig.

"It's super top secret," she said. "My family has such a big mouth. They've proven their inability to keep secret, so I just didn't go there."

The Masked Singer airs Wednesdays at 8 p.m. on FOX.
