Pop beauty Katy Perry has opened up about her decision to show less skin with the release of her new album, 'Prism'. 

Speaking about being a little more modest, Perry explained that she's never been one for nudity and the times she has shed her clothes for photoshoots she makes sure the pictures are taken in a way that give the illusion of perfection, because she isn't completely self-confident:

"Actually, I did take all my clothes off, for Teenage Dream. I was on a cotton candy cloud, showing my... back.  don't have the body for it. If I had, like, Rihanna's body, I'd take my clothes off. But I don't. I just hide my body in a way where you think I have it."

The 'Dark Horse' hitmaker added that she's done with being half-dressed in public for now, but might reconsider in her mid-30s, depending on how her career is going:

"Maybe when I'm 35 I will [take all my clothes off]. I don't need to do it now, because I've got great songs. If I get super-desperate, maybe I will then."
