Mackenzie Dern just proved she doesn’t need a fight night to leave fans knocked out. The UFC stunner traded the gloves for a barely-there blue bikini, and let’s just say the internet couldn’t tap fast enough on that like button. In the throwback post, Dern flashes her signature contagious smile while striking a playful peace-sign pose. The tiny string bikini hugged her athletic frame as she knelt in the sand, proving why she’s long been one of the UFC’s most-followed fighters outside the cage. With her beachy waves blowing in the breeze and her toned figure on full display, Dern had no trouble stealing attention from the stunning ocean backdrop.

The photo, which racked up over 45,000 likes, was captioned with a nostalgic nod to her love for Brazil, “How I miss this spot! Just a few more days for me to be back in Rio!” As always, Mackenzie’s fanbase wasted no time flooding the comments section with fire.

Others went straight for the knockout line, branding her a “smoke show."
Floating Into Balance

While Dern is usually known for grappling on the mats or throwing down inside the octagon, her Instagram proves she knows how to kick back, too. In one playful snap, the UFC star lounged on a giant donut-shaped float, flashing double shakas as she drifted across the water. With her long hair cascading down her back and the sun hitting just right, the post served as a reminder that Dern’s vibe isn’t all fight camp and weigh-ins, but she’s got a fun, carefree side that her fans can’t get enough of.
But behind the scenes, Dern’s life is anything but lazy-river simple. Earlier this year, she opened up about how she balances her grueling training schedule with raising her daughter. For Dern, the gym often doubles as “take your daughter to work day,” turning sparring sessions into family time. “It’s not always easy,” she admitted, but she says those mother-daughter moments are some of the most rewarding, even if her little one doesn’t always agree on what counts as fun.

Captioned simply “Sun kisses,” the post captured her natural beauty and carefree spirit.
Fans wasted no time flooding the comments with love. One admirer declared her “Beautiful,” while another filled their reply with endless heart emojis. Others couldn’t resist pointing out her glow, with one writing, "absolutely radiant.” The photo racked up over 71,000 likes, proving Dern doesn’t need gloves or a gi to command attention.
