Just as her Coast music video was about to launch, Hailee Steinfeld was flaunting her tight abs in a retro bikini on Instagram on November 11. The singer/actress shared a trio of mirror selfies of the ’70s-inspired look, which hails straight from the beachy music vid along with a couple of just-as-striking others.
Her BTS snaps went viral, and deservedly so: the eye-popping fashion aside, each photo was chock-full of chiseled curves and sexy vibes.

Hailee Teases Fans With Her Tongue Out

Hailee oozed sultriness from every pore as she posed with her hip cocked and her lips slightly parted in a provocative way. Serving cleavage in a low-cut top with a cute bow accenting the revealing neckline, she bared her sculpted midriff in a high-waist micro skirt that clung to her hips and skimmed her thighs.
The 25-year-old paired the colorful set with chunky bracelets in a deep, electric blue shade. Her cascading tresses absconded a pair of matching star-shaped earrings, flowing down her back and over her shoulder in loose waves.
Each selfie was more tantalizing than the other but where Hailee really got flirty was on the third slide. She playfully stuck her tongue out and peered directly into the mirror as if staring into her audience’s soul.

Watch Hailee’s Music Video Below

As covered by Diply , the Coast music video featuring Anderson .Paak is an ’80s and ’70s-inspired extravaganza and sees Hailee rocking her super-toned figure in a slew of retro outfits, including a plunging shimmering jumpsuit.
Released three months after the song first came out in July, it’s also a nod to Hailee’s collaboration with premium water brand, Core.
The music video has great humor in it and proves that, even though Hailee has shared that Coast was “years in the making” and is “the song of my dreams,” she doesn’t take herself too seriously.

Let’s Talk About Her Insane Abs

There’s definitely a big buzz about Coast these days but one thing that can’t escape attention are Hailee’s insane abs. Whether in the music vid or in her social media updates, they practically leap out of the screen.
The Pitch Perfect actress recently shared that she stays in shape by working out with her personal-trainer dad. Their sessions are all about bonding and loving what they do, she told Women’s Health in July.
Hailee also takes her hydration very seriously and is never without a bottle of water. (Her Core partnership makes perfect sense.) As for what she puts on her plate, the singer says she completely ignores fad diets and is all about getting the proper nutrition to fuel her body: “I eat so that I can train, I don’t train so that I can eat.”
