AceShowbiz - Supermodel Marisa Miller was once fired from her grandfather's company - for accidentally flashing her naval at co-workers. The U.S. stunner, who now strips off for Sports Illustrated and other top publications, was working as a secretary to make a little extra money as a teenager when her granddad called her into his office.

She recalls, "I was reaching up to put something away in a cabinet... and he saw my belly button, so I get called into the office... and he said, 'You're dressed really inappropriately. This is a professional environment and I saw your belly button.' "

"I was like, 'Grandpa, I was, like, totally stretched out. It's not like I'm wearing a crop-top or something!' But he fired me."
