When you're a huge pop star, people tend to say nutty things about you. But the single most outlandish thing ever said about Katy Perry was pretty unexpected: Earlier this year, she faced accusations of basing many of her fashion choices – and possibly her entire existence, somehow – on a buxom, brunette Archie Comics character named Katy Keene. And to be fair, there is a distinct resemblance between them – as well as a bunch of near-matching outfits.

Perry was well aware of the controversy when she spoke to senior writer Brian Hiatt for her Rolling Stone cover story. "I saw that a few months ago," she says in outtakes from the interviews, "and the Internet is so crazy. Like, that's crazy! I want to go get an MRI right now and have them look inside me and make sure I'm not a comic! But what freaked me out about it is, we looked into it, and it turned out she has a sister who's a redhead. And my sister is a redhead! And I was like, 'Fuck! Stop it!'"

But Perry cautions against taking the whole thing too seriously, or imagining that she actually did systematically plunder the iconography of an obscure old comic book character. "I mean, it's pretty interesting," she says. "But it's not that deep! Like I would have been, like a physicist if I were that smart, you know what I’m saying? If I was that smart and that calculated, I would be, like, something else."
