Jessie J is planning to shave her head for charity
The `Price Tag` hitmaker is known for her dark bobbed hair but wants to raise money for good causes by chopping off her locks and she insists she isn`t worried about having a buzz cut.
She said: "I`m shaving my head next year for charity - it`s definitely happening if I raise a million, which I think I will.
"I`ve spoken to a few celebrities who are interested too. I`m quite excited at getting rid of the bob. People say, `But your hair is so nice.`
"But I can wear wigs and no one would ever know. And if I can save some lives then that`s amazing."
Jessie feels she has been "chosen" to be a role model and so she never wants to let down her young fans, even though she knows that puts her under pressure.
She told Britain`s Cosmopolitan magazine: "I wasn`t like, `I want to be a role model,` but I always wanted to bring good.
"Sometimes you don`t choose things, things choose you and I feel like the role model thing has chosen me. It`s important to embrace the limelight and I know it sounds like a cliche, but the kids need me not to let them down.
"It is a pressure and the difficult thing is I`ve said I don`t drink or smoke, which is true. But every now and again I`ll have one drink and suddenly everyone makes out like I`m an alcoholic. It annoys me because it`s not like I`ve said I never drink, I`ve just said I`m not a drinker."
