Chrissy Teigen Flaunts Totally Nude Bod for Women's Health Naked Issue

The Sports Illustrated model covers the September edition of Women's Health UK -- AKA the "Naked Issue" -- where she poses completely nude on the cover of the magazine.

Looking gorgeous in absolutely nothing, her hair styled in tousled waves and rocking a giant smile on her face, the wife of John Legened confesses she has to hit the gym more often these days in order to eat what she wants.

"I used to take pride in the fact I didn't have to work out, and then I hit that age where you have to. I want to drink champagne and have hearty dinners, so I would rather work out for an hour and be able to do what I want," she tells the mag.

"I've always had to watch myself," she adds. "My family is not naturally thin and we put on weight quickly. I find low-carb works for me."

Teigen also says she'd love to have a baby with the "All of Me" crooner someday soon. "I'm waiting for things to slow down, but things don't seem to be slowing down, ever, so I think, 'Just have one and deal with it.' I'd love to have an excuse to be bigger," she admits. "People will know as soon as I'm pregnant because I'll stop drinking."

While Chrissy looks absolutely stunning in mag, the brunette beauty admits that she's gained a little bit of weight since writing her new cookbook.

"Working on the cookbook, I put on around 11lb in five weeks, despite doing regular workouts," she reveals. "Before, I was always thin and just had to tone up, but now I'm trying to keep that extra layer [of fat] off. I'm having a tough time getting back to my pre-cookbook weight. It's only 5lb, but it's frustrating… My tummy has always been my problem. I've never seen an ab, no matter how many crunches I do."

Teigen also talks about her friendship with Kim Kardashian, and says she'd love to have a family just like the Kardashians.

"Kim is lovely. I'll email her and she gets right back to me. It makes me feel like garbage because I'm like, 'I'm 10% as busy as you and I don't get back to people.' They are the most beautiful family. I look at them and think, 'How do I get this?'" she says.
