In a recent interview with Cosmopolitan, Perry revealed that when it comes to new material for her next album, we can expect to hear plenty of songs inspired by her ex-boyfriend and serial-heartbreaker, John Mayer.

“There’s no bad blood,” she said, “but I’m sure there will be inspired songs.”

Gracing the cover of the July issue of Cosmopolitan, Perry has just been named the magazine’s first ever global cover star, meaning that there were 62 different cover shots of her in total for the issue, and which she announced to her Instagam followers, “NBD just COVERing all 62 international editions of @Cosmopolitan’s July issue”.

Meanwhile, in his typically cool fashion, Mayer has pretty much responded to Perry’s comments with a ‘bring it on’, telling TMZ, “I have super strength for gang-ups. I’m fine. That’s what you’re supposed to do, man,” adding a quick, sly diss at his ex-girlfriend, “You’re supposed to write songs. You’re just not supposed to tell everybody you’re doing it.”

Ever the modest one, the singer-songwriter just couldn’t help himself by revealing, “I actually want everybody’s songs to go number one… I purposefully stopped writing hits to give other people a chance to have number one songs.”
