Kate Upton Tugging Down Her Bikini Bottoms Is 'Top Notch'

Kate Upton is making major headlines right now for a Sports Illustrated Swimreturn, and that only means one thing. Fans have been rushing to see the latest snaps, then going down the rabbit hole of throwbacks as they seek more photos of the 31-year-old model. In May 2017, a fan on Instagram shared a bombshell snap of Kate back in her SI Swim days. Looking drop-dead gorgeous by the ocean as she flaunted her curves, Kate sizzled in a colorful bikini, even using both hands to tug down parts of her briefs' waistband. Unsurprisingly, the fan sharing the image only had love for Kate as they called her "top notch."

Scroll for the photo, plus Kate's latest SI Swim snaps. Backed by crystalline blue waters and clear skies, Kate wowed as she flashed her eye-popping cleavage and curvy waistline in a plunging white bikini with thick, block-color straps in pastel orange and yellow.

Drawing the eye from her chest to her gym-honed abs, the mom of one kept her briefs itty-bitty and low-rise, with pops of green here bringing more jazz as she pinged her thumbs inside the green part of her bottoms. Kinda tugging her swimwear down a little, Kate shot the camera a piercing gaze, highlighting her baby blue eyes as she wore her signature blonde locks down.

Likely in her early twenties at the time of the photo, Kate stunned all rosy-cheeked as she wore dark eyeliner to bring out her light-colored eyes, also flashing her pearly whites as she smiled a little. "Well first of all of course I'm gonna pick Kate Upton to be first she is top notch @kateupton straight beauty," the fan wrote.

Talk now is of Kate's triumphant return to Sports Illustrated as she joins other former SI Swim faces in marking the iconic magazine's 60th anniversary. The photos showing Kate back in the bikini game this week make the 2011 Rookie of the Year a six-timer with the magazine. The star made her SI Swim debut back in 2011.

Posting to Instagram this week, Kate shared her bombshell return as she stunned in a plunging, red-cupped bikini with a girly pink frill. Rocking striped bottoms as she flaunted her sensational curves after the 2018 arrival of daughter Genevieve, Kate lifted her arms up above her head, smoldering with her blonde locks in beachy waves.

Speaking to People about her return, Kate said it was a "huge honor," adding:

“It really speaks to really where fashion is going and the message that [Sports Illustrated Swimsuit’s editor in chief] MJ Day wants to put out — women supporting women, showing different body types and having women speak for different things they believe in."
