JUSTIN BIEBER has come clean about the bad behavior that’s marred his recent career in a video posted on his Facebook page.

    The star had just finished taping the “Ellen” show earlier in the day. Bieber explained in his video that he felt nervous about how he would be perceived.

    “I was afraid of what people were thinking about me right now. I didn’t want to come off as arrogant and conceited basically how I’ve been acting in the past year, year and a half. I’m not who I was pretending to be. I’m a person who genuinely cares.”

    During his appearance on the show, he surprised the hostess with birthday gifts including flowers and a pack of Calvin Klein underwear.
