Justin Bieber’s reputation continues to take hits, as yet another video has surfaced in which he uses a racial slur. Over the weekend, a video from 2009 was released in which the then 14-year-old singer was seen telling a joke that included multiple uses of the word “n****.” Yesterday the U.K.’s Sun released another video, this time with the singer changing the words to his hit song “One Less Lonely Girl” to “One Less Lonely N****” and joking about joining the Ku Klux Klan. The new video appears to have been around the same time period as the first one.

The Canadian singer has had a difficult year. As U.S. Weekly summarized, his publicity team reportedly tried to buy the first video to avoid public backlash. Bieber was arrested for a DUI in January and is currently under investigation for attempted robbery.

Bieber issued an apology for the first video clip on Twitter, writing on Sunday that “as a kid, I didn’t understand the power of certain words and how they can hurt…I apologize for offending or hurting anyone with my childish and inexcusable mistakes.” He promised, “I am a man now who knows my responsibility to the world and not to make that mistake again.”

He has not yet commented on the second video.
