Teen music sensation Justin Bieber is splashed across this month's Vanity Fair cover.
The young music marvel told the magazine he had insomnia and a very overactive mind.
"I just turn over all night and think. My mind races," Bieber said.
"I think about all the things I didn't have time to think about during the day - like family and God and things that should be more important.
"I'm crazy, I'm nuts. Just the way my brain works," Justin Bieber told Vanity Fair for its current cover story. "I think differently -- my mind is always racing. I'm just...nuts. But I think the best [musicians] probably are."
When asked about his biggest music idols, Bieber put forward The Beatles, Michael Jackson and Tupac.
"I'm definitely influenced by Michael Jackson and Boyz II Men and people who were black artists -- that's what I like."
