“Heroes” star and, apparently, heroes of dolphins in Japan as well, Hayden Panettiere sure does keep herself busy (and yet available for paparazzi) these days. Which reminds me — how are the ratings for “Heroes”? Anyhoo, Hayden’s spotted here at a parking lot wearing killer boots, killer shades and killer tight pants. Judging by how fast she matures before our very eyes, I have a feeling that this girl will soon grace the covers of sexy magazines very, very soon. Nay or yay? YAY!!!
