LOS ANGELES — Usher says though Justin Bieber had a wild year, people shouldn’t count the pop singer out just yet.

“I mean more money more problems,” the R&B singer said in an interview Wednesday at the premiere of “Justin Bieber Believe” in Los Angeles. “The beautiful part about it is that those that are invested in a long-term story you understand that there are peaks and valleys in every person’s life some. Unfortunately the reality is he has to live with a camera in front of him, but what he chooses to do on or off camera is analyzed or scrutinized in some off way.”

Earlier this year Bieber was caught on camera clashing with a paparazzo. While touring the pop star fainted backstage at a London show and had to be taken to a hospital. These incidents came after photos of Bieber appearing to smoke marijuana hit the Web. During the summer, he also had to apologize by phone to Bill Clinton, for cursing the former president and spraying his photo with cleaning fluid in a New York City restaurant kitchen.

His longtime manager Scooter Braun agreed that Justin Bieber had a very crazy 2013.

“Pandora’s box was opened. I mean he got a little bit into trouble,” Braun said.

“Justin Bieber Believe,” which opens in U.S. theaters Christmas Day, captures a behind-the-scenes look at the 19-year-old star. Bieber will release a new album, “Journals,” Monday.
