Justin Bieber apologises for being a brat at Comedy Central roast: 'I lost some of my best qualities'

Justin Bieber has sent his apologies for being, well, Justin Bieber.

Speaking at the end of his Comedy Central Roast, the 21-year-old admits he wants to turn his life around.

"I've turned a lot of people off in the last few years," he said. "But I know I can still put out good music and turn everything all around.

"There was really no preparing me for this life. I was thrown into this at 12 years old.

"There were moments I am proud of and there are moments I am disappointed with myself for. But the things I have done, don't define who I am.

"I am a kind-hearted person who loves people. And through it all, I have lost some of my best qualities. For that, I'm sorry.

"I am looking forward to being someone you can all be proud of.

"Someone close to me once said, 'It's how you rise from a fall that truly defines you as a man.' I'm excited for that challenge. And I want to say thank you for taking this journey with me."

The singer went on to apologise for his behaviour, that includes throwing eggs at his neighbour's house. Yes, really.

"You have my word," he added. "I will not end up broken, pathetic, bitter or sitting on someone else's roast. I'm at a moment of change. This is a new day."

So what is the star doing next to "turn everything around"?

"I'm going to Vegas," he told the room of reporters. "On my jet, b----!"

Right…
