Petra Nemcova is always smiling and she always seems to be happy and this makes her more beautiful then she is. Would be nice to see all celebrities this happy and radiant, but we all have problems and no matter how much we try to hide them you still see them in our eyes. So, is the same with celebrities. They are human too. But, I think for Petra Nemcova nothing can change the happiness from her eyes. She is a survivor and she knows what real problems are.
