Justin Bieber: 'I don't want to make people feel uncomfortable'

'What Do You Mean' sensation Justin Bieber has admitted that being a role model to millions of youngsters has made him think hard about his behaviour and what he gets up to in front of the cameras.

During a revealing new interview with i-D magazine, the superstar confessed that he doesn't want to be pictured doing things that make fans uncomfortable, such as smoking marijuana:

"At the end of the day, there are people who don’t think that’s good and if they don't feel that’s good then I don't want to make people feel uncomfortable."

"I’m not going to put it in their face. You’ll never see me smoking. Because that is not who I am. If it’s something I do then it’s something I do, but it’s not who I am and what I want to put on blast for the world to see."

Earlier this week, Bieber confirmed details of a world tour that will promote his forthcoming new album 'Purpose' and he told Ellen DeGeneres that the jaunt is set to begin on March 9. Tickets are set to go on sale on November 16 and no specific dates or locations have been announced.
