Christina Augilera is having a pretty good month. Not only did she make Maxim's Hottest Pregnant Celebrities Ever list, she also landed the cover of Marie Claire in all her nekkid pregnant glory.

Baring it all for magazine while pregnant is still a relatively new phenomeon. Demi Moore created a furor in 1991 when she appeared on the cover of Vanity Fair wearing nothing but jewelery in her final trimester. Some retailors refused to carry the magazine, while others offered in wrapped in brown paper to protect the public from the site of a bare swollen belly.

Since then, many famous expectant moms have bared it all (or nearly all) for magazines, but for some reason an exposed pregnant body still seems to shake the sensibilities of many.
