Justin Bieber has poured his heart out in an open letter to his fans after cancelling the rest of his world tour.

The Canadian pop star sensationally announced last week that he was pulling the final dates of his Purpose tour "due to unforeseen circumstances" - which prompted a media and fan flurry.

Justin, 23, has addressed the cancelled tour for the first time, and said it was due partly to him wishing to have a "sustainable" career and future.

He told his fans he was "grateful" for the journey he was taking with them and for going through "this life" with them.

The Sorry hit-maker wrote: "I have let my insecurities get the best of me at times, I let my broken relationships dictate the way I acted toward people and the way I treated them!"

He added that he let "bitterness, jealousy and fear" run his life.

"I am extremely blessed to have people in the past few years help me build my character back up reminding me of who I am and who I want to be," he said.

Justin also candidly said he is "VERY aware" he will never be "perfect" and said he will keep making mistakes.

"But what I'm not gonna do is let my past dictate my future," he added. "What I'm not gonna do is be ashamed of my mistakes."

He continued: "I wanna be a man that learns from them and grows from them.!! I want you all to know this tour has been unbelievable and has taught me so much about myself..

"I am reminded of how blessed I am to have a voice in this world. I've learned the more you appreciate your calling the more you want to protect your calling. Me taking this time right now is me saying I want to be SUSTAINABLE.

"I want my career to be sustainable, but I also want my mind heart and soul to be sustainable. So that I can be the man I want to be, the husband I eventually want to be and the father I want to be."

He said he wanted his message to act as an opportunity for people to "know where I am coming from".
