No maternity muumuus for this mama-to-be!

While most pregnant women as far along as Jessica Simpson appears to be would be sporting billowy, loose fitting clothes, the Fashion Star mentor seems to only want clingy items that flaunt her growing bump!

In Los Angeles on Friday, the star, 31, hit up the posh Bel Bambini baby boutique for a shopping trip with her mom, Tina Simpson.

Jessica rocked a green knee-length dress worn under a black blazer and sky-high orange and nude platform heels.

In November, the star told Us Weekly that she plans to wear heels up until the moment -- literally -- she welcomes her and fiance Eric Johnson's baby into the world.

"I'm probably going to deliver my baby in these [4-inch YSL heels]," she joked to Us.
