Marisa Miller's Near Wardrobe Malfunction

Tears of joy from celebrities are usually reserved for such events as winning an Oscar, but being on the cover of a magazine? Unusual, unless you're Marisa Miller, the cover girl for this year's Sports Illustrated Swimsuit Edition.

"I started crying I was overwhelmed, I’m not really a crier but I turned into a big baby," she tells OK! of when she learned she scored the cover. "Also because everyone kept these little secrets from me and when it finally happened, everything just clicked to what was going on. What was so overwhelming is to know that a lot of people love and care about you to plan this whole thing out."

The unveiling was a big to-do, set up by her agent, who told Marisa she had a business meeting with a client. "I walked in this conference room, they open the doors, there's a camera crew, the editors, a big poster of the cover, champagne, flowers, and I was like, 'Whoa.'"

Landing the illustrious cover honor is something the 29-year-old bombshell doesn't take lightly and worked hard for, enduring 14-hour days shooting in body paint.

"The body paint is always a malfunction," she laments. "We start at 2 a.m. and end at four then run out on the beach shoot for 10 minutes, then it started raining and I’m in paint so I ran to the hotel. I didn’t know if it was going to run, but I didn't want to stand around to see what happens. But the paint's a little more durable than you think."

It was all worth it though for those sexy pics. And how does her husband, producer Griffin Guess, feel about them?

"Oh, no, he doesn't get jealous," she says. "He knows what he signed up for."
