Kate Upton's Mega Bikini Moments

In one of her three 2017 SI covers, Upton wears what might be her skimpiest swimsuit yet, which consists of an elaborate gold belly chain and a statement necklace.

In another 2017 SI cover, the supermodel poses in a white crochet monokini that doesn't cover up much.

In her third 2017 SI cover, Upton sports a sequin blazer instead of a bikini top and pairs it with simple white swimsuit bottoms.

The supermodel was quite the scene-stealer when she showed up in the 2014 romantic comedy, The Other Woman, wearing an itty-bitty bikini. It also helped that she was filmed running in slow-motion while sporting the swimsuit. 

In the 2014 Sports Illustrated Swimsuit issue, Upton dons a nude-colored bikini while posing for a zero-gravity, space-like photo. 

In July 2013, Upton was spotted in a sexy red bikini while hanging out on the beach in Nassau, Bahamas, with her Other Woman co-star, Cameron Diaz, during a day off from filming.

In her second cover for SI, the supermodel manages to pair a big winter coat with teeny bikini bottoms -- and pull off the look!

In her first Sports Illustrated Swimsuit cover, Upton is spilling out of a teeny, red bikini that ultimately put her on the map.

In July 2011, Upton walked the the runway in this cleavage-baring swimsuit during the Beach Bunny Swimwear show at Merecdes-Benz Fashion Week Swim in Miami Beach, Florida.
