Lorde revealed she turned down an offer to support Katy Perry on her upcoming PRISM tour because she wants to establish herself as an "independent" artist.

She said: "I think in the really early stages of an artist's career it's important for them to establish themselves for themselves. I'm just basically really stubborn and I want to be really independent. So I want to be headlining my own shows instead of supporting someone else. Which I think is fair enough."
