Kate Upton was on location for a Sports Illustrated swimsuit spread, and Mother Nature didn't want to cooperate!
Kate was sporting bikini bottoms, no top, and everything was going fine until a big wave came along, and woosh! Down into the water off the rock she went!
Not to worry, she is ok, but definitely the "skirt" she was wearing was drenched!
The video was muted due to language, but you can see it below!
