posed topless Thursday for a Sports Illustrated photo shoot in Aruba.
The 25-year-old covered her breast with her hands while posing on top of rocks in a tulle skirt.
Things got slippery and the star suddenly lost her balance and slipped off the rock.
The skirt fell down and exposed her bare butt. The photographer scrambled to grab her but the model was left soaking wet.
Kate shook it off and showed that she was a good sport, brushing off the incident unharmed.
She later changed into a barely there black thong bikini and a matching caged corset top.
As readers know, She was named Rookie of The Year in 2011 when she made her debut appearance on the Sports Illustrated Swimsuit Issue.
