The controversial singer Justin Bieber stunned the audience during Comedy Central Roast with a heartfelt apology he delivered after the comedic punches were thrown at him by many celebrity guests on Monday night.

There was a brief moment of silence when he started his sentimental note on how he had turned into a completely different person during the last 10 years in the music industry. Fans can recall a DUI arrest, multiple scandalous events including the controversial Brazilian girl he had been involved with and on and off relationship with Disney superstar Selena Gomez.

"There was really no preparing me for this life. I was thrown into this at 12 years old and didn't really know what I was getting myself into. There's been moments I'm really proud of and a lot of moments I look back and I'm pretty disappointed in myself for, but the things that I've done really don't define who I am. I'm a kind-hearted person, who loves people, and through it all I lost some of my best qualities. For that, I'm sorry. But what I can say is I'm looking forward to being someone that you guys can all look at and be proud of," the 21-year old superstar said on the show.

Bieber owes this change of heart to an unnamed person that he has loved and lost. But he further hints that this special person was thankfully present. He then thanked God for never giving up on him.

The Comedy Central Roast was a star-studded event which included Kendal Jenner and Kourtney Kardashian among the audience while the stage had Martha Stewart, Snoop Dogg, Kevin Hart, Dave Chapelle, Ludacris, Shaquille O' Neal, Will Ferrell as Ron Burgundy from the movie 'Anchorman' and others. Natasha Leggero had won the most comedic punchlines during the show.
