The latest celebrity said to be jumping on the nudie pregnant pictures bandwagon is Nicole Kidman, who was seen yesterday attending a "top secret" modeling session for a potential cover shoot with Frenchy photographer extraordinaire Patrick Demarchelier. While he's no Annie Leibovitz, and it's unknown which magazine this shoot was for, Demarchelier is a monthly contributor for Allure, Vogue, and Demi Moore's old knocked-up-while-nude stomping grounds, Vanity Fair. So whether or not Nicole is looking to appear on an upcoming cover of VF as Demi's successor is still unknown, but we took a look back at some classic big-bellied celebrity appearances in the past to see some glossy examples of what Kidman will be competing with in the Nude And Pregnant Hall of Fame:

Lisa Rinna posed much more naked than most in, oddly enough, Playboy for all those guys out there who just can't get off unless their centerfold is very knocked up, and Milla Jovovich posed behind a transparent sheet for Jane's body issue. Monica Belluci has taken it all off for VF before, but it was the Italian edition, which really isn't that big a deal. It's European!

Though she was nowhere near naked, the then-prim Gwyneth Paltrow did bare her pregnant belly for a W cover, while Heidi Klum might as well have been nude for the cover of Vitals while carrying Seal's spawn. And Cindy Crawford looked very Demi indeed, but in a more model-y way, on an older W cover.

Most recently, Christina Aguilera shimmied around a bed for a Marie Claire cover shoot. And of course, Demi Moore initiated the trend on her landmark 1991 Vanity Fair cover. But our favorite (if we really had to pick one) nudie pregnant shoot of all time goes to Britney Spears in Harper's Bazaar, mainly because the 2006 shoot was ironically seen as a surefire way to "come back." If only she'd known there was simply no "way to come back," she wouldn't have had to pose for those drag queeny photos at all.
