Victoria Justice, star of “Zoey 101” and “Victorious,” is ready to get her teeth into some gritty roles to shed her squeaky-clean Nickelodeon persona.

“I would shave my hair off for a role. I have never done that before so I don’t know if I have an odd-shaped head once it is all gone,” she told Page Six at the 21st annual ACE Awards Monday night at Ciprani 42nd Street. “I would not want to play an ax murderer, but I would love to play a complicated character like a drug dealer or someone addicted to drugs that is battling through that . . . I would be willing to not bathe for a week to get that gritty look.”

She added, “It is my job as an actor.”
