Hayden Panettiere Is Sort Of Being A Bitch To Milo Ventimiglia Oh readers, we can't tell how long we've waited for this day - the day that Hayden Panettiere became a genuine stroppy mare. We knew she had it in her, sure. But now it's here and, lord, it is beautiful. How much of a stroppy mare is Hayden Panettiere? Only stroppy enough to try and get Milo Ventimiglia sacked from Heroes because he split up with her last month, that's how much. Or maybe Hayden Panettiere has got Milo Ventimiglia sacked from Heroes. Or maybe Hayden Panettiere was sacked from Heroes instead. Nobody watches Heroes any more, so nobody really knows.
