The 26-year-old singer said his job encourages vanity, so he has removed the temptation of worrying about his looks and feeling self-conscious when he's trying to relax at home, reported Contactmusic.
"There is a certain amount of vanity that comes with this job, which isn't an appealing trait. You can find yourself inching over to that side occasionally because you see yourself in shoots and videos.
"I have got rid of all the mirrors in the house - when I come home I don't want to be self-conscious.
