Kate Upton is one of the hottest women in normal gravity, but I think she is now officially the hottest woman in zero gravity history.

Sports Illustrated is celebrating the 50th anniversary of the swimsuit issue and many of you have probably seen the awesome threesome cover. Well Kate Upton also got a cover for the issue, granted it is the back page cover, but still a cover. She also did a very unique photo shoot for this issue.

Kate Upton had the pleasure of going into one of the zero g planes that make you feel weightless. I have no idea how they officially work, but I know they go up and down real fast to make you weightless. I remember the guys from Wildboyz doing this and Steve-O threw up everywhere. No word on whether Kate Upton threw up on the plane.
