There was a story the other day about Hayden Panettiere being a bitch on the red carpet. Now there’s another one of her being a bitch on the set of Heroes. According to OK! Magazine, Hayden, attempting to wield what little power she has, is trying to get her ex-boyfriend Milo Ventimiglia fired.

“She refuses to be on the set at the same time as him,” the pal tells OK!. “She is making it difficult for everyone involved.”

Since the split, Hayden has been linked to a string of men including rocker Anthony Kiedis, 46, her ex Stephen Colletti, 23, and Gerard Butler, 39.

You’d think Hayden would tread carefully. Ratings for Heroes have been on a steady decline since the first season and she’s not even the most popular character, but may be the most annoying. That Japanese guy who wiggles his nose has a bigger fan base than her. That is to say, it would be fairly easy to put a bullet in the back of her character’s head and ice Hayden for the rest of the season. Wink, wink.
