'World's Sexiest Nurse' Lauren Drain Poses With Her Pants Undone & Rocks A Black Bra For Maternity Photo

Lauren Drain is rocking a bra and underwear in her latest Instagram photo. On Sunday, the pregnant bikini competitor and fitness model uploaded a picture of her baby bump. She also revealed that it's become difficult to wear certain clothing items since her belly has gotten bigger.

In the snapshot, Lauren -- who holds the unofficial title of the "World's Sexiest Nurse" -- is rocking a black Calvin Klein bra and matching underwear. Her top is stretchy, featuring an athletic cut with a V-shaped scoop neck and thick straps. The white band of the bra is emblazoned with the iconic Calvin Klein logo. The Instagram star's ample cleavage is on full display, partially spilling out of her bra.

Lauren's underwear also features the Calvin Klein logo on the waistband, which dips down below her baby bump. She's also rocking a "Canadian tuxedo" over her undergarments. Lauren is wearing a light blue denim jacket that is pulled down around her arms. The blonde's tight, distressed blue jeans also have been unbuttoned and unzipped to accommodate her baby bump. In the caption of her post, Lauren joked that the only way she can fit into her jeans nowadays is to wear them in this manner.

For her makeup, Lauren is sporting a smoky eye, dark brow, and glossy nude lip. She's also wearing bronzer that highlights her cheekbones. Her skin is flawless, and she has a gorgeous golden glow. Lauren is wearing her long hair in loose waves, which flows down her shoulders.

In the caption of her post, Lauren revealed that she is currently 32 weeks pregnant. One of her followers asked when her due date is, and she replied that it's supposed to be January 11. However, Lauren shared that she believes her daughter might arrive early.

Fans were quick to leave comments, telling Lauren that pregnancy looks good on her. She's been sharing a lot of her unique maternity looks on Instagram lately, including a lacy black bodysuit and booty shorts.

"Omg so dang gorgeous as always!!! Beautiful mama!!" commented one user.

"How do you slay pregnancy like this??? Gorgeous," another admirer wrote.

"Omg you're so bomb girl! You rock pregnancy girl!!" replied a third fan.

In the meantime, Lauren isn't letting her baby bump keep her out of the gym. In a series of videos that she shared on her Instagram stories, the fitness enthusiast showed off her impressive strength by performing weighted squats, which involved a barbell and trap bar deadlifts.
