Our second most quirky pop star, Katy Perry, has spoken to NYLON magazine about her new music, fiance Russell Brand and her thoughts on he fellow female pop stars.

KP knows who her rivals are but says she manages to differentiate herself from the competition by doing her own thing.

"You've got GaGa, who's like, from outer space; you've got Ke$ha, who's the beer-drinking, house-party girl; and then you've got Rihanna, who's transforming the urban world into her own outer space. But I feel like you're missing an Alanis Morissette, in 2010. I love how she was a voice for a lot of people who couldn't explain their feelings. But it's not like I'm not gonna compete. I love a good dose of healthy competition. It's not going to be the same that they're doing…"

But Katy isn't threatened by her closest rival...

"When I heard The Fame Monster, I was like, 'What the f*** is she talking about - teeth and he ate my heart and monster and dance in the dark and s***?' I thought she was such a shock jock. Then I saw her on the American Music Awards, and I was like, 'You're an animal of another kind, and we need you!' She's amazing. She's an entertainer, a visual arts. And her lyrics do mean things when you actually break them down."

And if you were waiting for Katy to talk about her beau, you won't be disappointed.

"Love has really affected [my songwriting]. I know how to handle a man now. So it's talking about the love rather than, you know, being annoyed with boys. He's like Jim Morrison meets Charles Manson meets Jesus meets a little bit of Elvis. He's a walking genius. Just standing next to him makes me smarter. He's good for me. He's not a pussy in any way, shape or form. He's the boss; he calls the shots. But I like that. I've been waiting for someone I couldn't steamroll."

We can't wait to hear Katy's new tunes...
