Justin Bieber Suffers From Insomnia, Thinks Haters Are Waiting for Him to Fall

The glut of information that fills Justin Bieber's adorable noggin each day -- music, fashion, concert dates and, yep, screaming girls -- is keeping the 16-year-old pop star up at night. In the February issue of Vanity Fair, Bieber admits that he sometimes suffers from insomnia, an affliction he says is caused by a hectic life that doesn't afford time to think about "things that should be more important."

"I just turn over all night and think. My mind races," he says. "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 but you don't have time to think about, because you just get caught up [in everything else] during the day."

One issue that looms large is the level of hatred directed his way from mostly male onlookers eager to see him fail. Bieber believes his "haters" are "waiting for that time when I make a mistake." If he does, he says, "they're gonna jump on it."

But Bieber tells the magazine that after watching so many young stars mire themselves in scandal (Lindsay Lohan and Demi Lovato, for example), he's convinced he'll weather the storm of his teen years relatively unscathed.

"I know I'm not going to make a life-changing bad decision, as some people have," he says. "I've seen it happen too many times. I could be my own worst enemy, but I don't want to mess this up."

On the topic of "haters," Bieber believes he'll convert some of them in a couple of years, possibly in a fashion similar to another Justin (Timberlake) when he came of age.

"For younger guys, it's like [they think] they're not cool if they come to my concert. That'll [change], I think; it'll happen, maybe when I'm 18," he thinks. "But meanwhile all their girlfriends are coming to watch me."

Attracting the opposite sex is not a problem for Bieber, but he also doesn't think it's entirely because he's famous. "Not trying to be arrogant, but if I walked down the street and a girl saw me, she might take a look back because maybe I'm good-looking, right?"
