LOS ANGELES: Justin Bieber chose an interesting way to start a new chapter in his life. Or at least try.

At the end of a massive celebrity beat-down at the Comedy Central Roast of Justin Bieber on Saturday night, Bieber apologized to the world from the stage for his prolonged spree of embarrassing tabloid headlines.

“I’ve turned a lot of people off in the last few years,” Bieber said, turning serious. “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,” Bieber added. “I didn’t know what I was getting myself into. 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 kind-hearted person who loves people. And through it all, I have lost some of my best qualities. For that, I’m sorry.”

Bieber called the celebrity roast, which comes after his 21st birthday, “a turning point” in his life.

“I am looking forward to being someone you can all be proud of,” he said. “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 sentiments came after an outpouring of abuse from roast master Kevin Hart and roasters such as Ludacris, Shaquille O’Neal, Snoop Dogg, Jeffrey Ross and even Martha Stewart.

Stewart gave Bieber advice for prison, a destination she called “inevitable.” Jeffrey Ross called Bieber the “King Joffrey of Pop” after the evil Game of Thrones character.
