Marisa Miller is about to pop, but that didn't stop her from showing off her baby bump.
The 34-year-old model, who is expecting a boy this month, posed nude for an Allure.com exclusive and opened up about what it's like to bare all during pregnancy.
"I always felt, even before I got pregnant, that it's better to accentuate your curves," Miller told the website. "A lot of women try to tuck their butt in or kind of slouch because they're trying to hide. Obviously, you can't suck it in, but it's important to really show off the belly. For some reason, for me, from the side it looks the biggest, so that's what I tried to do."
But Miller's belly isn't the only thing changing. The Sports Illustrated cover girl said her hair and nails are growing much faster, forcing her to cut her nails with clippers for the first time ever.
Miller, who will appear in the 2013 film "R.I.P.D." alongside Ryan Reynolds and Kevin Bacon, also shared her secrets for fighting stretch marks.
"My sisters both had babies this year and were really religious about preventative care," she said. "I'd been on Molly Sims's blog a lot-she was in her third trimester when I had just gotten pregnant-and she posted this recipe: shea butter, cocoa butter, coconut oil, and vitamin E. I made it myself, boiling the ingredients, and I poured it into mason jars. I've loved the community of women who share their tips."
Miller has had to cut back on her workout routine because of her pregnancy. Through her second trimester, the model was doing Pilates five times a week, but now she's mostly just stretching and breathing. She advised pregnant women to enjoy their extra pounds.
"Embrace everything and all the changes," Miller said. "I had never even owned a scale before, but gaining weight is part of charting your progress. Yes, I was seeing numbers I'd never seen before, but I let go of that because I had a new goal and focus. It's an adjustment, but it helps having a lot of positive support."
