Mom-to-be Emily Ratajkowski might have just won Halloween with her Demi Moore-inspired look.

The pregnant actress, 29, shared a series of images to her Instagram stories on Halloween, showing off her costume.

Wearing a white silk shirt, black lingerie, and a short, black wig, Ratajkowski posed holding her growing belly.

She also shared her inspiration – an iconic image from Demi Moore’s 1991 Vanity Fair spread, where Moore famously showed off her pregnant physique.

The original images were captured by Annie Leibovitz.

Ratajkowski announced she and husband Sebastian Bear-McClard are expecting their first child with an essay in Vogue.

“Who will this person be?” she wrote. “What kind of person will we become parents to? How will they change our lives and who we are? This is a wondrous and terrifying concept, one that renders us both helpless and humbled.”

The actress explained why the couple doesn’t want to reveal their baby’s sex.

“I want to be a parent who allows my child to show themself to me. And yet I realize that while I may hope my child can determine their own place in the world, they will, no matter what, be faced with the undeniable constraints and constructions of gender before they can speak or, hell, even be born.”
