Are Lorde and Katy Feuding?

Imagine this: You get a phone call from Katy Perry and she asks you to open for her on tour! Cool, right? Well, that's what happened to Lorde recently when she offered a spot on Katy's Prismatic World Tour. Unfortunatley, there was a problem she wasn't interested! Does she hate Katy or something? Nope- Lorde was just focusing on her own career! "I think in the really early stages of any artist's career it's important for them to establish themselves for themselves," the "Team" singer explains. "I wanted to be headlining my own shows as opposed to supporting someone else." Got it, Lorde!
