Joanna Krupa brought another meaning to the term beach bum down in Miami.
One minute the Polish model was like a fish in the surf ... extremely slippery when wet.
Then she was on land, where her husband, Romain Zago, unfortunately got in the picture and made sure she was protected ... from the sun.
Check out the vid -- pretty sure he didn't miss a single spot.
Joanna gave us even more proof ... her body's just fine. Totally fine.
