Kate Upton has been on the front cover of Sports Illustrated for the last two years in a row. In 2013 she posed her curves in an open parka and bikini bottoms in Antarctica and the year before, she posed in a skimpy red two-piece and was photographed nude inside the magazine except for a bikini made out of body paint. Her career took off after TMZ showed photos of the then 19-year-old nude on a horse.

Now Kate Upton lands a Sports Illustrated cover for the third time, in a creative fashion. Photographers decided to picture her in a zero gravity chamber -- meaning there'll be no gravity to hold back her assets. In the latest shoot, Kate Upton is wearing nothing but a small gold string bikini. The model and the Sports Illustrated crew did the shoot in a Boeing 727 airplane run by the Zero G Experience, which freedives to simulate the experience of zero gravity. The team shot photos and video of Upton floating through the airplane's cabin in her swimsuit.

Afterward the cover girl said, "It was so much fun, completely weightless, floating around, twirling. I was upside down and I couldn't even tell. It was one of my favorite experiences so far in my life," she said. "You have no control over your limbs and you're twirling you don't know what's the ceiling and what's the floor and it's a really cool feeling."

The 50th annual swimsuit edition of Sports Illustrated magazine features the backsides of models Nina Agdal, Lily Aldridge and Chrissy Teigen in the front. Former cover girl Kate Upton tweeted "OMG! So happy for @LilyAldridge @chrissyteigen and @NinaAgdal!! What a gorgeous cover!! Loving the booty for vday!"

Kate Upton was featured in the same magazine in a bonus flip cover on the back, the first time Sports Illustrated as done so. The cover shows the 21-year-old Kate Upton sitting in the shallow water of a Cook Islands beach in a pink bikini by Beach Bunny Swimwear and is entitled "Five Decades of Sexy" fashion retrospective.
