Jessica Simpson Nude Baby Bump Shoot with Elle: “I’m Having a Girl!”

Jessica Simpson posed in her birthday suit — Demi Moore-style — on the cover of the April 2012 issue of Elle magazine. Jess tells the glossy that she hopes her fashion-conscious genes will be passed down to her little one.

That’s right: The heavily pregnant singer-turned fashionista, 31, may look like her uterus is currently occupied by a small village of clowns, but it turns out Jessica is having just one baby — and it’s a little lady.

“”Eric is so athletic — we’re gonna have this athletic girl and I won’t even be able to take her shopping, ’cause all she’s gonna want is sports bras and Nikes! I swear, I will croak if she asks me for a pair of Nikes instead of Christian Louboutins!”

She and fiance Eric Johnson have already picked out a “non-traditional” name for their daughter.

“We’re sure. It’s nothing shocking and nothing you’ll have to add to the dictionary. Still, when people hear it, they’ll know…why.”

Recently-rehabbed actress Demi Moore set off the trend of celebrities baring their baby bumps at the newsstand with her belly-busting appearance on the August 1991 cover of Vanity Fair. Britney Spears and Christina Aguilera have followed suit in the years since.
