The 18-year-old - who was pictured smoking salvia through a bong last year - said she believes that you have to make mistakes in life to be able to learn.
Speaking to Australia's Daily Telegraph newspaper, she said, 'I mess up - there you go! But if you live your life trying to be perfect, you don't really live your life ever, because you don't really make any mistakes and at the end of your life you won't be very smart or wise.'
She added that she wants to be seen first and foremost as a musician.
'I don't lip-sync. I would rather someone say I sing like c**p, than have people see me lip-sync,' she said. 'I want to show people who I really am, more than just what they see on TV. It's all about the music.'
