Although the model wore black underwear, her chest remained…ahem…unsupported.
She was enjoying some private time with her husband Romain Zago on the deck of their yacht, without her bikini top! Pics are taken in Miami Beach.
Krupa's modeling career highlight was when she posed naked and steaming hot on the worlds most famous publication, the Playboy magazine.
Where Joanna took all of her clothes and posed completely nude for the eye of the photographer.
She also took dance lessons which have honed her over the years.
Another thing that Joana does behind the camera is managing her own business.
