Miranda Kerr is baring more than just her baby bump in the December issue of W.

For the magazine's family issue, she poses nude.

"Yes, I am pregnant. Four months along," she announced in August -- a month after broke the news.

Kerr's modeling days soon may be numbered.

"My ideal situation would be to live on a farm in a solar-powered house with a hammock and a vegetable patch," the model - who wed Orlando Bloom this past summer -- told Page Six Magazine in 2008. "When this is all over, that's where I'll be. I've always wanted kids, so someday, eventually, yes, it will happen."
