Justin Bieber keeps his cool on the latest cover of Rolling Stone, on newsstands this Friday (July 20).

Check out what the 18-year-old musician had to say:

On growing up: “I feel like I carry myself in a more manly way. I don’t carry myself as a boy.”

Manager Scooter Braun on girls perception of Justin and girlfriend Selena Gomez‘s relationship: “Yes, there’s gonna be some girls that if they see him with a girlfriend, it kills the dream – but there’s also gonna be girls that see him with a girlfriend, hear about the romantic things he does and want him even more.”
