Justin Bieber in Hot Water After Racial Slurs, 'Jokes'

"Never Say Never" star and crooner Justin Bieber is in more hot water - this time, it's an incident from his past, not present, that's bringing  criticism toward the Biebs.

On Wednesday, TMZ posted a video of Bieber, then 14, changing the words of his love song "One Less Lonely Girl" to some unfortunate new lyrics.

Bieber sings that there will be one less "lonely n*****." He adds: "If I kill you, I'll be part of the KKK."

Uh, yeah. That sounds pretty bad.

A source close to the singer, now 20, says that the video was made in response to a comedian parody, which included similar lyrics... though does not contain mention of the KKK.

This comes just two weeks after another old video surfaced, this one containing Bieber (for some reason) telling a racist joke on camera.

"Why are black people afraid of chainsaws?" He asks.

The answer, which he announced himself - well, just assume it contains the "n" word a few times.

Bieber has apologized for these videos.

"As a young man, I didn't understand the power of certain words and how they can hurt. I thought it was okay to repeat hurtful words and jokes, but didn't realize at the time that it wasn't funny and that in fact my actions were continuing the ignorance."

"I take my friendships with people of all cultures very seriously, and I apologize for offending or hurting anyone with my childish and inexcusable mistake. I was a kid then and I am a man now who knows my responsibility to the world and to not make that mistake again."

But other mistakes? Those seem sure to come.
