Shot by photographer Renell Medrano, the model posed totally naked in a sun-soaked room, showing off her her killer curves and growing baby bump.
In another series of artsy photos, the brunette beauty looks angelic, submerged in her bathtub as she sweetly cradles her belly.
The proud mom-to-be also posed topless on her bed, wearing just a comfy pair of sweatpants.
In even more sultry shots, the Inamorata swimwear designer covered up (at least a little bit) in a black unbuttoned oversized blazer and matching relaxed pants.
Back in October, Ratajkowski announced she and husband Sebastian Bear-McClard were expecting their first child. True to form, the fashionista broke the news on her social media with a highly-produced and stylized video, directed by her friend Lena Dunham, that featured the model stripping down naked to reveal her new curves and little baby bump.
The My Body author also debuted her bump as the digital cover star for Vogue magazine that month. In an essay for the magazine, she revealed she does not want to know the baby's gender.
"When my husband and I tell friends that I’m pregnant, their first question after 'Congratulations' is almost always 'Do you know what you want?'" she wrote. "We like to respond that we won’t know the gender until our child is 18 and that they’ll let us know then. Everyone laughs at this.
"There is a truth to our line, though, one that hints at possibilities that are much more complex than whatever genitalia our child might be born with: the truth that we ultimately have no idea who — rather than what — is growing inside my belly," she continued. "Who will this person be? 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."
Ratajkowski tied the knot with Bear-McClard in 2018.
