Petra Nemcova showed off her stunning model figure at Milan Fashion Week's Spring/Summer 2013 Pin Up Stars Catwalk.
The Czech-born model wore an orange string bikini with bear faces on the top as well as a dainty floral yellow bikini.
Nemcova has been unlucky in love. In 2004, her fiance, Simon Atlee, died during the 2004 tsunami in Thailand. Nemcova survived by hanging on to a tree for eight hours. In 2010 she got engaged to British actor Jamie Belman, but their relationship fizzled out two years later. This past spring she was linked to actor Sean Penn.
She has been active in several charity organizations, including creating the Happy Hearts Fund.
