Jessie J loves being a role model.
The 'Domino' singer says she wants to set a good example to her young fans and prove you can be successful without giving into peer pressure.
She said: ''You can be who you want to be without taking the path of cigarettes, alcohol and drugs. I base my confidence on purity. It's important for me to embrace being a role model, and that young people have someone to look up to who does that.''
Jessie, 24, also says it's important to believe in yourself and never give up on your dreams.
She told Top of the Pops magazine: ''You need to have self-belief, because if you don't believe in yourself then nobody else will believe in you.
''When a door closes in your face, it's not the end. It means there's a bigger, more beautiful door around the corner. You just have to go and find it.
''I'm addicted to performing, I'm someone who craves the stage. For those who have seen me live, that's where I'm most comfortable.''
