Justin Bieber has denied speculation that he is having a breakdown.

The singer has been accused of battery by his neighbour, who allegedly claimed that Bieber spat in his face and threatened to kill him.

He also made headlines during a recent incident-packed trip to London, where he showed up two hours late for a show, went around town wearing a gas mask and got into a verbal altercation with a photographer.

Bieber has now told US Weekly: "The biggest misconception about me is that I'm a bad person. I get upset about that.

"I have a big heart. I want to be a good role model, but some people want me to fail. I'm young and I make mistakes. That's part of growing up.

"I know who I am and I'm not gonna let negativity towards me bring me down. I'm a positive person and I plan on staying that way."

The 19-year-old continued: "This business can break you down, but I have a strong team around me, and my family and all the fans. The love overcomes the negativity.

"I'm not perfect but I'm growing and trying to be better every day. That's part of life."

The popstar also insisted that his recent collapse on stage was due to flu.

"The worst thing to me is disappointing my fans," he said. "We only had five songs left, so they gave me oxygen and I decided to finish the show and then go to the hospital. The show must go on."

The 'Boyfriend' singer also explained why he was pictured walking to his hotel without a shirt in freezing temperatures.

"I still had part of my tour wardrobe on and was rushing into my hotel," he said.

Hey ima 19 year old so its fine if i spit in your face.... what a complete tit.
