Lorde "forgets" to eat dinner.
The 18-year-old singer is usually accompanied on the road by her mother Sonja and says her parent's present helps keep her life normal.
She admitted: "I still forget to eat dinner or forget to do my laundry, so she keeps me moving."
The 'Royals' hitmaker admits her life has changed in a "crazy" way since she first found fame but she feels "very lucky" to have so many experiences.
She told the new issue of Australia's Vogue magazine: "It's crazy going from living in a country that feels kind of small -- and I'd never travelled, really -- then coming to LA or New York for the first time, and meeting all these people outside your group of friends from high school.
"The world has expanded for me in this incredible way. It's cool, and I'm very lucky that I get to surround myself with creative people who are clever and good at what they do."
While she enjoys going to America, Lorde - whose real name is Ella Yelich-O'Connor - feels most comfortable in her native New Zealand as she can lead a normal life there.
She explained: "It is easier to have a normal life back home. I think everyone knows that they're going to see me around, that I'm going to be buying gum from a gas station or whatever.
"The shine rubs off when you're like: 'Oh yeah, my friend met her in the supermarket the other day.' I think people are much more chill about it. Yeah, people are good there, respectful. I love living in New Zealand."
