In the past 12 months Justin Bieber's reputation has took quite battering due to the frequent run-ins with the law and his general bad behaviour, but it now seems the Canadian pop star is ready to own up to his mistakes.

Bieber has apologized for his year of bad behaviour 

On Wednesday (Jan 28th) Bieber posted a badly lit video of himself on Facebook opening up about the way he has been acting this past year. The 20-year-old, who seemed quite emotional in the clip, offered an apology for his "arrogant" and "conceited" behaviour.

The video was uploaded shortly after Bieber made a surprise appearance on The Ellen DeGeneres Show, which he confessed to being incredibly "nervous" about.

"I think I was nervous because I was afraid of what people are thinking about me right now," he explained in the video. "It's been a minute since I've been in a public appearance, and I didn't want to come off arrogant or conceited or basically how I've been acting the past year, year and a half."

Bieber, who was named the highest-earning celebrity under 30-years-old by Forbes, has frequently found himself in trouble with the law, including a DUI arrest, Vandalism charges and assault charges.

"I'm not what I was pretending to be. Why I say I was 'pretending' is often we pretend to be something we're not as a cover up of what we're truly feeling inside. And there was a lot of feelings going on in there," he continued. "Just being young and growing up in this business is hard. Just growing up in general is hard."

Bieber also admitted he felt "awkward" when speaking with Ellen because he thought the audience and viewers were "judging" him.

"...I really want people to know how much I care, how much I care about people, and how I'm not that person to say, 'I don't give a f**k,' you know? I'm not that kid, I'm a person who genuinely cares," he added.

Hopefully this is the turnaround Bieber's dedicated fan base are hoping for.
