In the accompanying interview, Katy spoke about a range of topics, including her hugely successful career as well as her first year of motherhood.
One point that came up in the interview was the fact that, despite more than a decade in the business and nine No. 1 hits to her name, Katy has yet to win a Grammy.
"No, I've been nominated 13 times before," Katy said. "To be honest, I always go by numbers, and they don't lie. And I'm good with that."
And then, when asked what makes her feel powerful, Katy explained that career achievements weren't at the top of her list and it was instead about her self-image.
"It's not necessarily any of my achievements on paper," she said. "It's just my day-to-day mental health and making sure that I'm happy."
