Turns out, the "Dark Horse" singer shared a ton of other interesting stuff with them that didn't make it into the mag. For example, she hates fame and thinks it can actually become quite disgusting - especially if you're famous for nothing.
"I never wanted to be famous," she revealed. "That's a byproduct of what I do. Fame is truly a byproduct of the dream that I had. People want to be recognized for their work, but nobody wants to be famous for nothing. Fame is, I think, disgusting...Useless fame is disgusting. I think if you've got a talent or something to offer, a creative thing to offer to the world, then I think that's beautiful. But that famous for nothing thing is kind of gross. It's a bummer."
Hopefully she isn't too bummed about her own fame, then, because she's obviously not famous for no reason. Speaking of which, Katy isn't obsessed with topping the charts, she's more interested in experimenting with her art and having a varied body of work.
"I don't want to have to conform to try and do that," she explained. "I don't want to have to play something I'm not to get that Number One or whatever. That's not music. That's math. And I don't want to be that."
Oh, and the third thing we learned about Katy from the Rolling Stone "cutting room floor," she loves Tumblr and even gets a lot of her style influences from there.
