Demi Moore created a major frenzy back in 1991 when she bared her baby bump --- and everything else! -- on the cover of Vanity Fair.

"The shot that ended up being on the cover wasn't even done for the magazine," the actress, now 49, told V magazine in '08. "The [photographer] Annie [Leibovitz] called, we kind of joked, and I said it would be amazing if they would do this on the cover."

And now, a heavily pregnant Jessica Simpson, 31, is following in Moore's footsteps, posing nude on the April cover of Elle.

The first-time mom-to-be also shocked fans by revealing to the mag that she's having a baby girl!

"She," Simpson, engaged to former NFL pro Eric Johnson, says of the baby.

Other stars who've pulled a "Demi" and stripped down for a cover include Christina Aguilera, Britney Spears and Cindy Crawford.
