Hayden Panettiere Doesn’t Play Well With Others

Oh sure, Hayden Panettiere can play catch on the set of Heroes in Los Angeles, but according to OK! Magazine, she’s not playing ball when it comes to getting along with her co-stars—especially her ex-boyfriend, Milo Ventimiglia.

A mutual friend of Ventimiglia and Panettiere’s says that Hayden, 19, is pulling a diva routine on the set, in possible hopes of sabotaging her former beau’s career. (Panettiere and Ventimiglia, 31, broke up in February.)

“She refuses to be on the set at the same time as him,” reports the friend. “She is making it difficult for everyone involved.”

Ventimilglia, meanwhile, is “not going to play any games or stoop to her level,” the source adds.

Panettiere’s rep denies the allegations, but the supposed shenanigans would certainly fit into the pattern of Hayden’s recent mood shift. The actress freaked out on reporters during a recent fundraiser in Hawaii, telling the journos that they’re making her life “misery.” Guess she’s deciding to spread the misery.

Careful, Hayden; with Heroes struggling to stay alive amid miserable ratings, your attitude might just prove to be the third strike for the show.
