'Roar' hitmaker Katy Perry has praised her boyfriend John Mayer's "genius" mind, and now she wants to donate his brain to science and figure out "how all these sparks work".
Katy Perry marvels at her boyfriend's intellect claiming his songwriting ability proves it and she has told him his brain should be examined to help learn his secrets.
She told Billboard mag: "He literally is a genius, as is evident from his songwriting.
Adding: "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.' "
The 28-year-old singer adds Mayer is an accomplished word puzzle solver being able to complete crosswords in under 10 minutes.
Perry: "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."
Her kind words follow John complimenting his girlfriend recently, describing her hit 'Roar' as a "massive" track.
Mayer added Roar' is in my life. I remember hearing it, going like, 'Wow what an interesting experience' to hear something that you identify as massive before it's massive.
"I thought it was a really sweet, unforgettable sort of experience to hear someone's work while they still have a very nascent relationship with it.
Mayer continued saying - "In a way you get swallowed up by it, it's so big. Because it's such an incredibly big song that it doesn't need you to tell anybody, while you're eating lunch, [that] millions of people are going to be dancing on tables to that."
