Olivia Dunne Doing Gymnast Splits In String Bikini Highlights Her 'Nice' Butt

Olivia Dunne is still turning heads with her 2025 bikini action as fans rave over her Sports Illustrated Swim runway walk. In May 2025, the 23-year-old landed her Cover Girl status with the iconic magazine, but there was more than just her shoot. Partaking in SI Swim's show at Miami Swim Week in June of last year, Olivia wowed while strutting her stuff in a skimpy bikini, delighting fans with a reminder of her gymnast skillset as she dropped into a perfect split on the catwalk. Showcasing her killer curves while flaunting her muscular frame, Olivia reminded the cameras of her flexibility and appeal. For one fan, though, it was all about the blonde's backside.

Scroll for the video. Sending the cameras a big smile while modeling a polka-dot monokini with a bikini feel, Olivia stunned with her rock-hard abs and killer legs on display.

Walking barefoot as she flashed her cleavage in her plunging swimsuit, the New Jersey-born star stuck to black and white, adding pops of red from feminine bows at the chest and hips.

Rocking a cheeky thong and halterneck design that highlighted her gym-honed back and shoulders, Olivia blew a kiss before dropping jaws with her split. Landing on the floor with ease, Olivia held her position for a few seconds before getting up and walking back down the runway.

"Modeling," a caption read as the X fan feed reposted the footage. "Drop it like it's hot," one fan said. Another complimented the Vuori Clothing ambassador in a more adult way, saying that she has a "great a**." Olivia made her SI Swim debut in 2023. One year later, she returned for a shoot in Portugal before making 2025 headlines for her Cover Girl shoot. This time, SI Swim jetted the star out to Bermuda.

Posting the above photo on her X last May, Olivia Dunne told fans: "I’m officially a Sports Illustrated swim cover model!!" 

"Fun fact, I was shooting on a fractured kneecap, so poses like this and the cover shot kind of hurt, but it was honestly so worth it," the influencer later admitted while discussing her headline-making cover. SI Swim has featured an array of high-profile celebrities in recent years, not limited to SKIMS founder Kim Kardashian, actresses Megan Fox and Salma Hayek, plus singer Ciara.

In these photos, Olivia Dunne shared stills from a video of her beam routine. Easing herself into a perfect side split, she flashed her peachy rear while in a cheeky black leotard, flaunting her agility and her rubber-band flexibility. Olivia went viral with her TikToks during the pandemic and has since become a full-blown celebrity with a seven-figure income from her online endorsements.
