As well as being one of the most successful pop stars in the world, Katy Perry is also one of the most beautiful so there is no doubt that many men can only dream about dating her. Unfortunately this isn't going to change anytime soon as Perry thinks dating "non-famous guys" can be a negative thing.

"I've done that before," she told Rolling Stone's most recent issue. "It's not that they have to be famous, although there's a level of understanding when they're in the same business, you know?"

"They understand what it means when you're tired from a show or the tour's exhausting you or if an interview went wrong-they know all the ins and outs, so you can just walk in to the house with a certain face and they understand, you know? Rather than, like, having to explain everything and that takes two, three hours," she added.

In the candid interview, Perry also opened up about what she learned when going through a divorce with Russell Brand in July 2012.

"Now I know-first and foremost, self-love, and then give love away," she explained. "Back then it was mostly just me giving love away with no self-love. I went through my 'return of Saturn,' is what they call it."

Perry also claims to find fame "disgusting" 

But being in the public eye this time around cannot have been easy, and Perry also echoes this when explain why she hates fame.

"Fame is, I think, disgusting, and it's really hard to separate your public life from your personal life," she said. "I only ever just wanted to make music and be on stage and play, and offer up my perception of how I view the world, through the songs that I write. But then there's a lot of different things that come with it, and I call them trade-offs."
