Say what you will about Justin Bieber, but the man seems to have acquired a sense of humour recently. Justin flexed his self-irony muscles during a dedicated Comedy Central roast on Saturday,  where the topics ranged from his poppy tunes, to his run-ins with the law, to his overall obnoxious behaviour.

Gone are the Biebs  Baby days.

And his roasters... well, even some of Bieber's closest collaborators had a go - from head roaster Kevin Hart, to  Ludacris, Shaquille O'Neal, Snoop Dogg, Jeffrey Ross and even Martha Stewart, there was no mercy for the Biebs. 

It was all in the name of tough love though. As Hart said at the beginning of the night: "Tonight we're going to give what his parents and the legal system should have done years ago, we're going to give this boy an a**-whoopin' "

And oh, did they ever. 

"He may have turned 21, but Justin will always be a baby to me. Since babies (urinate) everywhere and never know when to shut up," said Baby collaborator Ludacris. That was one of the softer jabs.

Ludacris added. "Justin Bieber wants to be black so bad, he's actually seen Kevin Hart's movies in theaters."

It's safe to say, Justin took some abuse. He took it all in stride though, since, as he announced at the beginning of the night, it was all meant to be a learning experience.

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."

He also called the roast, which took place just days after his 21st, a "turning point". Fingers crossed, guys.
