Katy Perry covers the new issue of Rolling Stone magazine, and the 29-year-old singer gives a refreshingly candid interview with senior writer Brian Hiatt about everything from Kim Kardashian's butt to the possibility of being a single mom. What?!

On her controversial decision to have big-bootied mummies dance onstage for her Prism tour, Katy tells the mag:
    "As far as the mummy thing, I based it on plastic surgery. Look at someone like Kim Kardashian or Ice-T's wife, Coco. Those girls aren't African-American. But it's actually a representation of our culture wanting to be plastic, and that's why there's bandages and it's mummies. I thought that would really correlate well together It came from an honest place. If there was any inkling of anything bad, then it wouldn't be there, because I'm very sensitive to people."

So what's her take on "cultural appropriation"? The singer says, "I guess I'll just stick to baseball and hot dogs, and that's it. I know that's a quote that's gonna come to f*ck me in the *ss, but can't you appreciate a culture? I guess, like, everybody has to stay in their lane? I don't know."

As far as having kids someday, Katy proclaims that she'd be fine doing that without being married...or even involved with a guy!
    "I want to be doing that in the right time. And that's not in the next two years, you know? Maybe it's in a five-year plan, but I need to really be able to focus 100 percent of my attention on it. I don't really want to take the child on tour. Not until, like, birth through five is over. I don't need a dude. I mean, Neil [Patrick Harris] and David, their twins are beautiful. It's 2014! We are living in the future; we don't need anything. I don't think I'll have to, but we'll see. I'm not anti-men. I love men. But there is an option if someone doesn't present himself."

We love her honesty!
