Kate Upton famously defies gravity on a daily basis, and was likely Sports Illustrated's inspiration to have the buxom blonde pose for photos inside a zero gravity chamber.
Clad in a tiny gold bikini, the 21-year-old model learned that what goes up will not always come down in the Zero Gravity Plane at the Space Coast Regional Airport at Cape Canaveral.
The photos featured inside Sports Illustrated's special 50th anniversary Swimsuit Issue, are a nod to Jane Fonda's weightless striptease from the 1968 film "Barbarella." And though Fonda achieved her airborne scene with help of camera tricks and Plexiglass, Upton's floatation is real and was experienced inside a "modified Boeing 727 flown in a parabolic, roller-coaster maneuver," according to NBC News.
No doubt after posing in Antarctica in a bikini for the magazine's 2013 Swimsuit issue, wiggling in zero-gravity seems like it would be a welcomed experience.
