Katie Austin Leaves Little To The Imagination In Daring New SI Bikini Shoot

Katie Austin is turning up the heat in paradise!

The fitness influencer and TV host has once again teamed up with Sports Illustrated Swimsuit, this time for a sizzling grotto shoot that highlights her strength, confidence, and undeniable star power.

Shot in a natural rock-lined lagoon, the photos capture Katie Austin in her element, giving off bold, beautiful, and radiating fierce feminine energy as she celebrates her stunning cover moment.

In the first photo, Katie Austin lies effortlessly across textured rock formations as crystal-clear water surrounds her.

Wearing a sleek, charcoal-gray string bikini, her wet hair cascades over her shoulder while her piercing gaze connects directly with the camera. With one arm stretched over the edge of the rock and her body partially submerged, the pose exudes a raw, earthy sensuality that blends seamlessly with the natural setting.

In another captivating shot, Katie arches her back gracefully, tilting her face toward the sky with her eyes closed as water droplets trace her glowing skin. Her bikini hugs every sculpted curve, highlighting her athletic frame while the shimmering ripples of the grotto dance around her.

"Part 2... the grotto, with the BTS," she captioned the post. "Some of my favorite shots from the 2025 issue. (Side note: this underground cave in Bermuda was FREEZING!!)"

"This is INCREDIBLE!!!! Gorgeous as always," one of her fans commented.

"So cool (guess literally too lol) and stunning!!!" another said.

Katie Austin isn’t just owning the beach. She’s redefining what it means to be fierce and free.

With a radiant smile and sun-kissed glow, Katie hangs effortlessly from a wooden frame, playfully glancing over her shoulder. Dressed in a cheeky brown bikini, her toned physique is on full display, framed by lush greenery and the rustic charm of the wooden cabana.

In another snap, Katie takes daring to a new level in a barely-there crystal chain skirt, going topless while covering her chest with her hands. The sunlight catches the teardrop jewels, giving the illusion of water droplets clinging to her body. With waves crashing behind her and a sultry, direct gaze, this bold and breathtaking photo captures raw feminine power wrapped in golden-hour glamour.

"Get your copy of Sports Illustrated Swimsuit hitting newsstands today!" she captioned the post, which was shared on May 14.

"AWWWWW.. my BEAUTIFUL daughter!" Katie's mom, Denise, commented. "I admire her positive spirit, and it’s such a JOY to watch her fulfill her dreams!!!!!! I am bursting with pride, and I am so happy for you!"

"You look amazing!!! Congratulations," one of her fans said.

Katie Austin traded the cover glam for some laid-back luxury in her April photo dump, and fans are loving the vibe.

In one of the standout shots, the Sports Illustrated stunner proves she knows how to unwind in style, giving off effortlessly cool energy while catching rays by the pool.

"I loved April so so much," she wrote in the caption. "Trying to slow down as much as I can to be with this version of myself. Never felt so at peace with the current stage of my life."

"Beginning the day with gratitude sets the tone for the whole day!" one of her followers commented. "You are amazing!"

"Yes, queen," another said. "Inspiring us all the way."

The fitness guru and entrepreneur recently marked the 7th birthday of her wellness app with a joyful beachside moment, complete with pastel balloons, ocean views, and plenty of gratitude for her ever-growing community.

Radiating joy, Katie beams as she runs barefoot across the sand in a lavender one-piece swimsuit, clutching a festive slice of cake in one hand and a bouquet of oversized pink balloons in the other. The coastal breeze plays with the ribbon streamers as the sun catches the shimmer of the sea behind her.

"Happy 7th birthday week to my first baby Katie Austin App!" she began her lengthy Instagram caption. "I started with literally six virtual workout classes, homemade iphone graphics, and just me myself and I running every d-mn part of it for the first years... and now we’ve evolved to over 425 classes, 15+ programs, thousandssss of members, and a whole d-mn TEAM."

"This is so cute!!!" one of her followers commented.

"Legitimately the app that changed my opinion of working out and my body back in 2019," another follower shared.

Back in March, Katie Austin served vacation goals in the best way possible. While soaking up the sun in the Bahamas, the fitness model and entrepreneur took a moment to unwind on the shoreline, and the view couldn’t be more breathtaking.

"Bahama Mama," she captioned the photo dump from her vacation.

"All the working out is paying off for that bikini body," one of her fans commented.

"Omg you're such a goddess," another said.
