Jessica Simpson paraded her pregnant and naked body on the April cover of fashion magazine Elle for all the world to see her growing baby bump. The 31-year-old singer and fashion mogul proudly showed off her curvy body and tweeted to fans, My Elle cover comes out today!! I'm a lil nervous but I've never felt more beautiful or empowered. I hope you like it!!!

Jessica Simpson told USA Today that she couldn't wait to posed naked for the cover of Elle magazine at a whopping 170 pounds.  Normally I'm hoping to be 107 pounds and I don't eat, but I ate cheesecake before we shot, she told the publication.

I wasn't nervous at all, she said. Normally, I'm so shy. I'm not the person you see photographed in a bikini on a beach. But for some reason, being pregnant, it's so easy for me. I feel so comfortable in my skin.

The 31-year-old told Elle magazine that she feels more confident now than ever. I'm loving every moment of it, I have to admit, she said. It's funny because I feel more comfortable in a bikini now when I'm pregnant than when I was before. I've become like a nudist or something. I don't know; I just celebrate my body so much more.

Simpson said that when she wore a bikini in her younger years, she used to draw on abs with eyeliner. I would not suggest people do that, 'cause it's not cute. You could tell somebody did it, she said laughing.

The blonde beauty might have a tough time breaking her pregnancy eating habits, which started with salted cantaloupe and have moved onto cheesecake.

Now cantaloupe is fine, but we have moved onto cheesecake, she said. I had cheesecake for breakfast this morning. Lunch? No. I had fried chicken.

Her pregnancy diet has come into question before and some health experts have expressed concern over her alarming weight gain.

According to an article from InTouch Weekly via Baby Center, Jessica Simpson's drastic weight gain could put her at risk for gestational diabetes, hypertension and other pregnancy complications. Why would you deliberately sabotage your body with unhealthy, fatty foods? nutritionist Jackie Keller told In Touch Weekly last month. You're not supposed to eat twice as much -- you just need 300 extra calories a day. The recommended gain for a woman at a healthy weight is 25 pounds, reported InTouch.

The Stir by Café Mom discussed Simpson's pregnancy diet, which reportedly has consisted of buttered Pop Tarts, peanut butter and jelly shots, Cap'n Crunc, Kraft Mac 'n' Cheese and cheesecake. Her current diet sounds like the menu at a sixth-grade slumber party -- after the parents have gone to bed -- or more accurately, a stoner's dream. I'm sure it's fun to eat, but it can't be good, wrote Nicole Fabian-Weber of The Stir.

If you happen to gain more than 35 pounds while you're pregnant, fine, whatever. Everyone's bodies -- and pregnancies -- are different. But would it hurt Jess to at least try to eat something green once in a while? If not for her, for her growing baby? I'm not a doctor, but I'm pretty sure all the sugar and fat and processed-ness of the food Jessica is inhaling is going to her baby, as well. I mean, that is why you can't drink booze while pregnant, right? Fabian-Weber added.

In interviews thus far, Jessica Simpson has only laughed off her pregnancy diet and cravings. However, supermodel Gisele Bundchen might not think it is such a laughing matter.

In a March 2010 interview with Vogue, Gisele discussed her first pregnancy with son Benjamin and made a point to mention how health was a top priority throughout the nine months.

I did kung fu up until two weeks before Benjamin was born, and yoga three days a week. I think a lot of people get pregnant and decide they can turn into garbage disposals. I was mindful about what I ate, and I gained only 30 pounds, said the Brazilian beauty.

What to Expect detailed a healthy pregnancy diet that included the following: The Pregnancy Diet is built around a few basic principles (which are actually pretty similar to the basic principles of healthy eating at any time in life): Avoid empty calories and junk food, provide your baby with a regular supply of good nutrients, and eat the right quantities of the right foods each day.
