With just hours before she marries Kris Humphries, she’s now revealed some hints about what guests can expect at Saturday’s ceremony in Santa Barbara, Calif.:
While Vera Wang is designing it, Kim’s pal Nicole Richie also had an influence. Richie told her, “‘I had this vision for your gown, just hear me out. I think you should go super classic, really old Hollywood,'” Kardashian says. “‘Think museum. You can’t go with something trendy.'”
“She came over and was drawing out all these things. It completely changed what I thought I was going to go with.” Which, Kardashian says, can be described as a timeless look. Another hint? “There might be more” than two dress changes throughout the night.
2. The Bridesmaids Dresses Aren’t Green
What about those supposedly green bridesmaids dresses sister Kourtney Kardashian Tweeted about? It was a red herring, says Kim, who let out a little laugh when she revealed to Seacrest that “Kourtney and Khloe keep on Tweeting all the wrong information” about the wedding.
3. She’s Hasn’t Been Calm the Whole Time
Kardashian has reveled in her calmness throughout the hectic wedding planning – but now admits to one crazy spell.
“I think I had my freak-out moment a week ago,” Kardashian says. “From Kris’s dogs in my space to his shirts on the floor to going over budget to everything you could possibly think of,” she says. “I mean, it’s ridiculous issues that I guess everyone goes through. Planning a wedding is so much work. I had no idea.”
4. Yep, She’s Marrying the Right Guy
“When you know you know,” she tells Seacrest. “We’re having so much fun we just get along so well, he just lets me be me. And we have such a good relationship,” she says, adding, “It’s such a normal, healthy, trusting, easy relationship.”
5. Her Dad Will Be There in Spirit
Kardashian told Seacrest that Bruce Jenner will be walking her down the aisle. But her father, the late lawyer Robert Kardashian who died in 2003, will be there in spirit.
While the wedding will deliver “glitz and glam,” Kim, who says she’ll be “Mrs. Humphries” at home and Kim Kardashian “on the street” once she’s married, says it will also “be so intimate and so just really heartfelt.”
Asked if she’ll carry anything on her down the aisle to remind her of him, she says, “I’m having something always with me. These are the moments you wish my dad could be here. You’ll feel the presence of my dad. I’ve had my moments where I’ve cried to Bruce, and it’s been emotional. I wouldn’t be human if I didn’t.”
