Bieber, now 20, admitted to his wrongs in a statement to British tabloid the Sun, which first obtained the pair of calumnious videos in which the singer liberally uses the N-word.
"Facing my mistakes from years ago has been one of the hardest things I've ever dealt with," the international pop star told the newspaper (via the Toronto Sun). "But I feel now that I need to take responsibility for those mistakes and not let them linger. ... At the end of the day I just need to step up and own what I did. ... Once again I am sorry for all those I have let down and offended."
"I just hope that the next 14-year-old kid who doesn't understand the power of these words does not make the same mistakes I made," he added.
The blundering teen idol also posted a page from Scripture on his Instagram account about sinners taking refuge in Jesus Christ to remove their sins. The page also quotes three Bible verses.
The singer's camp claimed to TMZ that Bieber had simply been doing a parody of a parody when he sang the song, in which he transposed the N-word for the word girl and joked about joining white supremacist group the Ku Klux Klan. He also said that his mentors — singer Usher Raymond and actor Will Smith — had reprimanded him for making the videos and took further action to show him how hurtful the remarks could be.
Scooter Braun, who manages Bieber and discovered the YouTube sensation, presumably addressed his client's missteps on Instagram late Wednesday.
"Some mistakes have no excuses. They are just wrong. But how a man reacts to those mistakes. . . How he owns it and learns from it. . . That defines him more than the mistake itself," Braun wrote, quoting himself at the end of the post.
The singer issued another apology earlier this week regarding footage showing him at age 15 telling a racist joke in which he repeatedly says the N-word in the punchline.
"I thought it was OK to repeat hurtful words and jokes, but I didn't realize at the time that it wasn't funny and that in fact my actions were continuing the ignorance," he said. "Thanks to friends and family I learned from my mistakes and grew up and apologized for those wrongs. Now that these mistakes from the past have become public I need to apologize again to all of those who I have offended."
Bieber and his camp have had a rollicking year of negative publicity thanks the the star's January arrest and simultaneous spate of other legal battles stemming from an egging incident, an unrelated attempted robbery case and several other controversies, including a petition to deport the rabble-rouser to his native Canada.
