In 1991, Demi Moore made having a baby bump chic when she posed on the cover of Vanity Fair heavily pregnant and nude.

Since then, dozens of famous moms-to-be have struck Moore-like poses with their child in utero. Earlier this year, a very pregnant Claudia Schiffer was photographed by Chanel designer Karl Lagerfeld for German Vogue, and this month Orlando Bloom's supermodel wife Miranda Kerr -- seen after the jump -- took it all off for W magazine at six-and-a-half months pregnant.

Hollybaby Executive Editor Kathy Campbell says these shots are the celeb equivalent of getting a belly cast or creating a lasting memento of their pregnancy.

"I think being pregnant is a very special time in a woman's life, so why not pose to capture that special moment forever? There are plenty of women who do belly casts, so this is just another way of capturing it. I think it's beautiful," Campbell said.
