Pregnant Marisa Miller proud of baby belly

Pregnant supermodel Marisa Miller had no qualms baring all for a new magazine shoot because she is proud of her baby belly.

The former Victoria's Secret regular agreed to pose nude for the new issue of Allure, in which the 33 year old reveals she is nine months pregnant and due any day.

She says, "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 (belly) in, but it's important to really show off the belly."

The model admits the most challenging thing about pregnancy has been the weight she has piled on.

She explains, "I had never even owned a scale before... 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."

The California beauty and her music producer husband Griffin Guess revealed they were set to become first-time parents in June (12). The couple wed in 2006.
