'As Long As You Love Me' hitmaker Justin Bieber has revealed that he keeps talking about his mistakes in the public sphere because he really needs the world to realise that he has changed his ways. 

Speaking to Hero magazine, the Canadian heartthrob explained that he wants people to understand how truly sorry he is for his past behaviour:

"I hope people felt the sincerity in my apologies. There are a lot of things that have happened in the last couple years that I'm not very proud of, and I feel a responsibility to my fans and to the public who believe in me to make it right."

"I hope everyone believed it--because it was honest. It's definitely hard having so many people judge you from a distance. Sometimes you just want to explain yourself, but then that's giving into gossip and it makes things worse. It's a tough line to walk."

It was also confirmed today (April 29) that Bieber will make a cameo in the upcoming 'Zoolander 2' movie. He shared a photograph of himself pulling the 'Blue Steel' pose with actor Ben Stiller via Twitter and Stiller then retweeted the image.
