Milo Ventimiglia has come under fire for cutting his hair.

His latest cropped-style is a big departure from his usual floppy look and the Heroes star admits some of his fans have been upset about his change of appearance.

“Some fans seem to hate it but I needed to grow up. I have had fans come up to me demanding to know what I have done with my hair.”

The 32-year-old actor - who previously dated his Heroes co-star Hayden Panettiere - also revealed he is now too old to play teenage roles so needed to change his looks in order to get offered more roles.

“I think there was a moment where my Heroes character Peter Petrelli needed to step out of the lost little boy kind of innocent persona. It also coincided at a point in my life where I can’t play these young teen roles anymore, but I still look young so I’m like what do I do? I’ll just pack on some weight and cut my hair. It helped.”
