In Billboard Interview Katy Perry graces the front cover of the Billboard magazine for its latest issue and share intimate details that have before been revealed.

The 28 year old singer discusses her divorce from English comedian Russell Brand and reflects on what a dark time it, even questioning if she wanted to "continue living".

Their break-up eventually inspired the song 'By The Grace Of God' as she explains "That song is evident of how tough it really was at a certain point".

"I asked myself, 'Do I want to endure? Should I continue living? All the songs are real-life moments. I can only write autobiographically. I put all the evidence in the music. I tell my fans if they want to know the real truth about stuff, just listen to the songs."

However, now the 'Teenage Dream' singer is on top of the pop-music world and has a new man in her life, fellow singer John Mayer.

She tells Billboard, "He literally is a genius, as is evident from his song writing. I always tell him, 'Darling, you know I'm going to have to give your mind to science after you've passed, because we're going to have to understand how all these sparks work."

Perry also revealed what goes down in the bedroom, "We'll be in bed, and he'll be doing the crossword puzzle. Every night, he tries to finish it in under 10 minutes. When he puts his mind to something, he really gets it done very well. I always ask for his help".

Crosswords? That isn't exactly what fans of Mayer and Perry would have imagined when thinking of their bedroom!

Katy also revealed that her next track to follow the globally successful 'Roar' will be power ballad 'Unconditionally' from her upcoming 4th studio album 'Prism'.

'Prism' is set for release on October 18th 2013.
