Gymnast Olivia Dunne Kneeling In Skimpy Bikini Should 'Stop Gaining Weight'

Olivia Dunne turned heads in May when she debuted her Sports Illustrated Swim Cover Girl photo. Posting on Instagram to mark another career milestone, the 22-year-old dropped jaws in a tiny bikini, posing on her knees from shallow ocean waters. Enjoying her glam shoot while in Bermuda, Olivia highlighted her curves and sensational abs for a reminder of her gymnast figure, but some fans were out to body-shame her. Olivia, who largely received love from her Instagram followers, was shaded by users on rival platform X, where one hater told her to "stop gaining weight." Olivia, who works out on the regular, is considered very slender and often the subject of envy on account of her ultra-toned body.

Scroll for the photo. Parting her legs a little as she enjoyed crystalline ocean waters, Olivia lifted one hand to her head while stunning the camera in her mismatched swimwear.

Rocking slightly sparkly bottoms in dark green, the LSU graduate added a zebra-print top in black and white, opting for spaghetti straps and a plunging neckline. Flashing her incredible abs and gym-honed hips, Olivia dazzled with a golden tan, completing her beachy look with her light hair worn down.

In a caption for her 5.4 million followers, Olivia wrote: "I'M A SPORTS ILLUSTRATED SWIM COVER MODEL," adding: "Somebody pinch me! Thank you @mj_day for making my dreams come true, and @wattsupphoto for capturing this moment make sure to get your magazine! ;)"

The post earned fire emoji from former pro golfer Paige Spiranac, plus a like from actress Jamie Lynn Spears. Fans weren't too sure elsewhere, though. On Olivia's X post, some questioned why SI Swim was choosing a slender, blonde woman over someone who might represent a more diverse demographic. "Really glad to see Sports Illustrated embracing plus-size modeling again," one reply read. Then again, another fan seemed to be of the opposite opinion.

Fans might be thinking how the comment could even have entered the user's head, given that Olivia Dunne is often celebrated for her muscular, petite frame.

"Stop gaining weight," the troll bluntly wrote. Another fan asked how Olivia was "fat" but still not too curvy up top. Olivia showed off her slender bikini body in another SI Swim snap in the above photo, this time slipping her curves into a skintight, printed swimsuit. She's also opened up about the shoot.

“I can’t believe it. Oh my god. That photo is so good. That is crazy, I am a Sports Illustrated Swimsuit cover model. This bikini ... this was the one. I felt like such a baddie in it. This is the best day of my life. This is so exciting," Olivia Dunne told SI Swim about becoming a Cover Girl.
