Hayden Panettiere has a hot way older man [1] and a hit show [2] so it's no wonder she wants to stay in shape. Check out her grueling workout routine video here [3]. Methinks she got a "skinny Starbucks" [4] to help stay slim. As for her super cas look, well Hayden did admit that her fashion sense changes pretty frequently in the February issue of Lucky magazine [5]. She said, “Right now my style is very frenetic. It seriously changes as quickly as my mood.” Or maybe she's just saving all her primping for her dates/hand-holding sessions [6] with Milo.
