The pop superstar, who has gained global fame with hits including "Firework", "Roar" and "Dark horse", has always been candid about her constant struggle with darkness, and how she overcomes it.

Asked how she manages to push herself to write upbeat songs when she is down, Perry said: "Actually, I think it's kind of like, my higher self or my better self from my spirit side kind of just takes the wheel and says, 'scoot over, I'm gonna start channeling a little inspiring message for you from the heavens and hopefully it will inspire you to continue further and therefore maybe inspire someone else'." "When I write songs like 'Firework' and 'Roar', it's not because I'm like 'Yay', it is like 'I'm really bummed' and I just have to push myself.
