Kate Upton Shows Off Her 'Big Boobs' In Unbuttoned Braless Jacket

Kate Upton's fans had plenty to look at when a recent X post offered up a four-image collage of her. The Sports Illustrated Swim model, who shot to fame with her 2011 cover for the magazine, flaunted her curves in a desert shoot in these photos, modeling an array of skimpy outfits with nearly all flashing her famous cleavage. Channeling cowgirl accents in one snap, Kate flaunted her curves in an unbuttoned, sleeveless gilet, turning heads with her bombshell figure while attracting comments. Kate, 33, had some fans discussing her shape, with one praising the modeling industry for "allowing" her to have "big boobs."

Scroll for the photos. Displaying her ample cleavage in a cut-out white bra in one photo, Kate flashed her sizzling curves close up, adding pops of gold from a bust clasp while going all windswept.

Posing amid dry, parched earth as she knocked the camera dead in bombshell mode, the mom of one went barely there in a slinky, sparkly green dress in another image, this time flaunting her cleavage more obviously as she opted for a just-about-covered finish.

Getting down and dirty in a third photo, Kate sat on the ground, rocking a cream-colored gilet while going both shirtless and braless. The Vosa Spirits partner, who rocked a little fringe here, added funky shades to accessorize her skimpy look, also showcasing her blonde hair styled into bouncy curls. Kate also offered a view of her curvy backside, wearing a flimsy slit dress with a wispy feel and a butt-baring design.

Fans rushed to comment. While one created a poll and found that over 70% of viewers found Kate Upton "hotter than Sydney Sweeney," another wrote: "For some reason, she was the only runway model allowed to have real curves and big boobs at the time. The rare exception. But now they even let not only fat but obese women do some runway. Can't discriminate now, can we?"

Kate Upton fronted media outlets in May 2024 as she made her triumphant return to SI Swim. While she modeled a ruffly pink-and-red bikini for her legendary cover, fans also got a more demure look as the stunner flaunted her jaw-dropping figure in this black, criss-cross swimsuit.

Speaking to SI Swim about how he got Kate into shape for her shoot, trainer Ben Bruno revealed: "Training-wise, she pushes herself very hard, but she’s also great about listening to her body and not overdoing it."

Continuing, he added:

"She likes to lift heavy weights (hates anything over 6 reps haha) and that’s what we do most of the time, but we also do some cardio 2-3 times a week, either after strength workouts or on separate days."
