Kate Upton's Super Sexy, Gravity-Defying Bikini Photo Shoot!

The super sexy 21-year-old super model recently did a zero gravity shoot in a weightless Zero G airplane for Sports Illustrated's 50th anniversary Swimsuit Issue. The shoot took 4 years to put together.

Kate showed off in a gold bikini from Target.  Upton posed seductively as she spun around, looking hotter than ever! 

 The super model has been SI's cover girl for the past two years and we've been anxiously awaiting this issue. These amazing photographs of Kate are far from disappointing! 

Upton also can be seen on the back cover of Sports Illustrated's latest Swimsuit Issue, wearing a pink bikini that definitely shows off her famous curves!

The issue went on sale Feb 18th 2014.
