Katy Perry calls John Mayer 'genius'

Pop star Katy Perry wants to donate boyfriend John Mayer's genius mind brain to science.
The 'Roar' hitmaker, who has praised her boyfriend's intellect, said she has told him that his brain should be examined to help learn his secrets, reported Contactmusic.
"He literally is a genius, as is evident from his songwriting. 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'," she said.
The 28-year-old singer added her musician lover can finish word puzzles in 10 minutes and is always determined.

"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.
