KATE UPTON on Sports Illustrated..

Her fans would already say she's out of this world.

And that certainly proved to be the case as Kate Upton posed under zero gravity conditions for a one-off photo shoot for Sports Illustrated's 50th edition.

Clad in a tiny gold bikini, the model swung upside down and all around as she was photographed in a Zero Gravity Plane at the Space Coast Regional Airport at Cape Canaveral in  Florida.
