Hayden Panettiere We reckon Heroes cutie Hayden Panettiere doesn't have a mean bone in that petite little bod of hers.

So what's with all the goss that she's been throwing a fit on set?

Specifically, Hayden has been accused of making life difficult for her Heroes co-stars by refusing to be on set at the same time with her co-star - and rumoured ex boyfriend - Milo Ventimiglia.

According to reports, she's even tried getting Milo fired from the show.

But now the 19-year-old has hit out at the said rumours, to set the record straight.

She told InStyle mag: "I don't think I'm an unpleasant person.

"The thing that bothers me most is when people make up stories about me being rude or unpleasant," she continued.

Hayden and Milo - who were first linked together back in December 2007 - reportedly split in February.

But we knew all along that Hayden was a classy chick.
