Pregnant women, like chicks with hairy armpits, is still relatively taboo in this society in that if you admit you find pregnant babes "hot" people tend to look at you like you're some sort of freak.
In spite of this, however, there have been a few "famous" chicks who have posed au naturale while they were preggers. Here are a few of the most notables ones:
Demi Moore is perhaps the most famous-and infamous-celebrity who posed starkers while preggers on the cover of Vanity Fair back in the 90s (a couple of years before she got paid over $12 MILLION to show her, uh-hum, talent in the, uh-hum, classic film Striptease).
Actress-turned-reality-star Lisa Rinna posed starkers for Playboy twice, the first time back in the 90s while she was preggers. (This was, of course, back when PB was still a viable men's mag).
Singer Christina Aguilera posed in ze buff a couple of times in different magazines whilst pregnant. (Is this what she meant when she sang that "Dirty" song?)
Britney Spears posed nude when she was pregnant while hitched to that white-dancer-faux-rapper-guy-what's-his-name or whatever.
Jessica Simpson showed her "famous" baby bump on a magazine cover ala Demi Moore. (And, no, she hasn't been paid several million dollars, unlike Demi, to show her, uh-hum, talent. Yet!)
Natalie Portman also pulled a Demi Moore and posed while pregnant in Vanity Fair, though she wasn't as nude as Demi was (though Natalie DID show her ass-literally!-in VF some years before).
So a Kardashian posed naked while she was pregnant. Yeah, I know, I'm shocked too!
Embattled #MeToo actress Asia Argento posed starkers while preggers years ago BEFORE she became an embattled #MeToo actress. (And, if you want to see WHY Asia is "embattled", Google it.)
OK, this isn't a naked pregnant celebrity. It's not even a real chick, but somebody got the bright idea of putting out a "pregnant" Spider-Woman after the PCers got-of course!-butthurt over THIS "sexist" SW comic book cover showing her, er, butt.
Speaking of butts, here's Christina Aguilera showing off her butt BEFORE she became preggers. (Again, I'm shocked!)
