The 20-year-old made the surprising admission in an emotional video posted late Wednesday to his Facebook page.

"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 and a half," Bieber said in the dark and grainy recording titled "Here we go."
Bieber made the missive last night after he taped the episode of the popular daytime talk show. A clip of the show, which airs today, can be seen here.
The appearance marks Bieber's first in a lengthy absence from the talk show circuit, and he admits he was nervous. He also expressed a desire to change his public persona.
"I’m not who I was pretending to be," admitted the young star. "Often we pretend to be something we’re not as a cover-up of what we are truly feeling inside, and there were a lot of feelings going on in there."
Star's shifting image
The singer rocketed to fame at age 13, when record label executive Scooter Braun discovered the Stratford, Ont.-raised Bieber on YouTube. In Wednesday's Facebook confessional, Bieber admitted that growing up in the music business has been "hard."
He also expressed a desire to brush off his bad boy image.
"I'm not that kid. I'm a person who genuinely cares and, although what's happened in the past has happened, I just want to make the best impression on people, and be kind and loving and gentle and soft."
The internet star-turned-international celebrity appears to be attempting a image makeover after a year of legal troubles and negative headlines.
"I think it’s just cool to be able to laugh at yourself," Bieber said in his interview with DeGeneres. "I’ve done some things that might not have been the greatest."
Bieber is also offering himself up to be the butt of the jokes on an upcoming Comedy Central Roast.Suggest a correction
