Hailey Bieber Shows Off Her Rock Hard Abs in Sports Bra After Posing in Skims Lingerie Campaign

Hailey Bieber is that girl.

Bieber, 29, proved that her hard work in the gym is paying off while snapping a mirror selfie. In the pic, which she shared via Instagram on Tuesday, June 23, Bieber flexed her abs while wearing a sports bra and spandex. Her bra featured a square neckline, black thong straps and a stone-colored stripe across her chest. Bieber completed her look with a navy zip-up hoodie, which she wore undone.

Bieber added a touch of sparkle to her look with stud earrings. She went makeup-free in the pic and wore her brunette hair slicked back in an updo.

The Rhode founder’s look comes after she posed in lingerie for Kim Kardashian’s Skims. In the campaign, she modeled the brand’s Everyday Cotton line in a number of ensembles.

First, she rocked a back bralette featuring a deep V-cut neckline and a G-string. She sat on the floor while tugging on her straps and gave the camera a dramatic gaze.

Bieber made her look even hotter with brown eyeshadow that was smoked out and matte lips. Her hair was styled in a messy — but chic — blowout.

In another shot, Bieber slipped into a pastel pink bra and mid-rise underwear. She also rocked a nude bra and matching thong, which hugged her hips, and a square-neck bralette.

Bieber opened up about the line in a press release statement shared with Us Weekly, saying, “For me, great basics are the foundation of every wardrobe. The Everyday Cotton collection has all the qualities I look for — it’s soft, comfortable, and easy to wear no matter the occasion. These are the pieces I find myself reaching for again and again.”

Kardashian, 45, also touched on the collection and gushed about Bieber’s “unique ability to make even the simplest pieces feel elevated.”

“Her approach to style is effortless, which made her the perfect person to bring Everyday Cotton to life,” Kardashian added.
