Heroes' flaxen-haired cheerleader wants Peter Petrelli dead. Now that Hayden Panettiere has stopped dating Milo Ventimiglia, she's miffed that producers insist on keeping him on set.

According to OK! Magazine Hayden supposedly:

refuses to be on the set at the same time as him," the insider says. "She is making it difficult for everyone involved. [Which Panettiere's rep denied].

And as for Milo well:

"He's not going to play any games or stoop to her level," said the snitch.

But think about it: what if Hayden did get former beau Milo Ventimiglia canned, and then the show's producers turned around and axed her as well for being an ungrateful little so-and-so? That would go a long way towards making Heroes watchable again. So yes, Hayden is totally right that NBC should change around it's million-dollar television series to suit the whims of her personal life. Ventimiglia should TOTALLY be fired. Hayden, please throw a tantrum and hold your breath until you turn blue, while knocking over delicacies on the craft service table. We've discovered that's always the best way to make a point.
