LOS ANGELES, June 5 (UPI) -- Justin Bieber has issued a new apology for more racist remarks he made as a teenager.
The controversy began Sunday when a video surfaced of a 15-year-old Bieber making a joke using racial slurs. He apologized the same day the footage was released, and said that "as a kid, I didn't understand the power of certain words and how they can hurt."
A second video emerged Wednesday that captures Bieber as he sings a racist parody of his song "One Less Lonely Girl." The singer replaces "girl" with a racial slur in the lyrics, and jokes about joining the KKK.
The star is 14 years old in the second video, and reportedly endorsed its release in order to take responsibility for his actions. He issued a second apology in a statement to E! News on Thursday.
"Facing my mistakes from years ago has been one of the hardest things I've ever dealt with," the 20-year-old says. "But I feel now that I need to take responsibility for those mistakes and not let them linger."
"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 years ago," he adds. "At the end of the day I just need to step up and own what I did."
