One of the things I love about Petra Nemcova is that she’s always willing to bust out that supermodel cleavage of hers for a good cause. So here she is looking red-hot at a Fashion Week gala dinner in Prague for her personal charity, the Happy Hearts Fund. And Petra should be glad to know that she’s already making a big difference. Because I don’t know about you guys, but my heart is feeling very happy after this. …Your heart is located in your pants, right? I never paid very good attention in school.
