Right on cue, pregnant Victoria's Secret model Alessandra Ambrosio is the latest celeb to do a riff on Demi Moore's 1991 Vanity Fair cover by posing sans clothing, cradling her prominent belly for a famous fashion photography duo. She's already walked the runway, posed (clothed) for a Spanish magazine and Twitpic'd pregnant, so this was a natural next step for the model, who's pretty used to wearing minimal clothing.
Ambrosio, who is naked, pregnant and, duh, gorgeous, in the above photograph, was shot by Mert and Marcus--not for a national magazine cover, but for a jewelry ad.
It's probably not the first thing you noticed about the photograph, but Ambrosio is sporting a selection of shiny gems by Brazilian jewelry company Vivara. Does her black-and-white, pregnant, naked (and amazingly svelte?) bod make you want to buy them? And will her son one day be proud to have contributed to this moment?
