The 21-year-old singer admitted he is struggling with fame and said he can see similarities between his situation and that of Amy, who died in 2011 at the age of just 27.

He said: "You get lonely, you know, when you're on the road. People see the glam and the amazing stuff, but they don't know the other side. This life can rip you apart.

"I feel isolated. You're in your hotel room and there are fans all around, paparazzi following you everywhere, and it gets intense. When you can't go anywhere or do anything alone you get depressed. I would not wish this upon anyone.

"I watched the Amy Winehouse documentary on the plane and I had tears in my eyes. People thought it was funny to poke her when she was at rock bottom, to keep pushing her down until she had no more of herself. And that's what they were trying to do to me.

"I just want people to know I'm human. I'm struggling just to get through the days. I think a lot of people are."

Justin also claimed people have struggled to accept mistakes he makes because his image used to be so wholesome.

He told NME magazine: "It's because of the way the 'Justin Bieber brand' was portrayed. I was a wholesome pop star who was so amazing who had nice hair and a f***ing image that no one could ever live up to.

"So when all this happened people were like, 'Woah, let's rip him apart'. If you see Ghandi roll up a blunt, it's different to seeing Ryan Gosling roll up a blunt. You wouldn't give Ryan Gosling a hard time."
