“I think that having a song and a video about tearing Katy Perry down, that's not women's empowerment,” she told Glamour. “We all do things that aren't, but I have to ask myself, Am I content with calling myself a feminist? Yes, because I speak out.”

The 24-year-old continued: “I'm not afraid to talk about the fact that women get paid less than men in the United States and how unfair that is. Talking about it at all is doing the work.

"And I think every woman does her part in some way. But I think in certain situations, certain people could be doing more if they're going to claim that as part of their brand.”
