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.
