Justin Bieber Apologizes for 'Arrogant' and 'Conceited' Behavior on 'Ellen' 

Justin Bieber attends the Grand Opening of West Coast Customs Burbank Headquarters at West Coast Customs on Dec. 7, 2014 in Burbank, California.

The star posted a confessional video on Facebook Wednesday night alongside the message "here we go." 

He begins by explaining that he taped Ellen earlier in the day (the episode airs Thursday), and since it was his first public appearance in quite some time, he was really nervous.

"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."

"I\'m not what I was pretending to be," he continued, referring to his childish behavior and run-ins with the law. "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.

"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 concluded.
