Justin Bieber is having a Donald Sterling type of week...

Justin Bieber might want to start working on another apology after a second video has been leaked showing the pop star using the N-word and joking about joining Ku Klux Klan.

Just days after apologizing for a video in which a then 15-year-old Bieber is seen telling a racist joke and using the slur, this new video -- obtained by British tabloid The Sun -- shows him singing his 2009 hit, “One Less Lonely Girl,” but changing the worlds to "One Less Lonely (N-word)." He also sings about the KKK. Bieber had apologized for the earlier video, blaming his insensitive words on his youth.

Meanwhile, TMZ reports that the guy who leaked the first video of Bieber, did so after Bieber's lawyers refused to pay $1 million to keep it under wraps.
