Kate Upton stunned fans with her space-inspired Sports Illustrated Swim shoot, one reposted on Instagram two summers ago. In August 2023, a fan feed showed the model in an eye-popping gold bikini, but it was the floating-in-space setting that made things unusual. Posing from her trip on a Zero Gravity Corporation flight, Kate highlighted her killer figure in a plunging swimsuit, leaving little to the imagination as she was photographed from various angles. The mom of one had fans going nuts, with one seemingly very keen on her chest. Ahead, see the photos, plus Kate's hottest shots.

Scroll for the photos. Appearing to float mid-air while on a pretty convincing space shuttle set, Kate flashed her ample cleavage and killer waistline while stripped to a skimpy string bikini.
The 2024 SI Swim Cover Girl was rocking one of her tiniest bathing suits to date, handling it like a pro as she flashed her long legs and toned tummy.

Stretching her arms out in one photo, Kate posed with models dressed as astronaut crew on either side of her. In another image, the bikini bombshell shot the camera a sultry, playful smile while nearly popping out of her bikini top. Wearing her hair down, Kate showed off her gorgeous blue eyes, also sporting a matte face of makeup for a flattering finish. The photos date back to 2014 when Kate went "zero-G" for SI Swim.
"We have been almost everywhere in the past 50 years with SI Swimsuit, but we have never done anything like this. It was certainly the most out-of-the-box shoot. Once again, Kate surprised us all with how she handled modeling in weightlessness," photographer MJ Day stated at the time.

Quick to comment, one fan said: "Girls, hurry up and bring this hairstyle back." Another merely wrote: "Omg boobies."
Kate has made a career from showing off her bombshell swimsuit body, although it's worth noting that she was initially encouraged to take another path on account of being too fat for the modeling industry. The wife to Justin Verlander, who keeps in shape, is known for being body positive, also for posting her training sessions on Instagram. She trains with trusty trainer Ben Bruno.
