The 16-year-old star - who was catapulted to the spotlight with her huge hit single 'Royals' - doesn't want to spiral out of control like former teen star Britney who was put under involuntary psychiatric hold in 2008 or end up like Amy, who died of alcohol poisoning in July 2011 aged 27.
She insists she won't drink alcohol and puts her sensibilities down to the way she was raised.
She told The Sun newspaper: ''I'll never go off the rails like Britney, or do an Amy, because my upbringing was so normal. I can't touch alcohol at my age and I'm not sure I even want to when I'm older.''
Lorde - real name Ella Yelich - also insists she won't let fame change her and aims to stay grounded.
She said: ''Six months ago, no one knew who I was and now fans chase my car. But I'm never going to change or let fame get the better of me.''
Lorde - who was raised in Auckland, New Zealand - doesn't like the lifestyle in Los Angeles and can't imagine herself living there.
She added to The Sun newspaper: ''I don't think I could ever live in Los Angeles. It does something to your soul. The place really infects people - if I stay there for too long I start being a freak. All this is just fantasy land as Lorde.''
