TMZ has posted a video that shows a 15-year-old Justin Bieber telling an extremely offensive joke while shooting his 2011 documentary, 'Never Say Never.' The video was originally leaked on The London Sun's website.

In the clip, Bieber is taped telling jokes with a group of friends.

He asks: 'Why are black people afraid of chainsaws?"

A friend off camera pleads with him, "Don't even say it."

Bieber then tells the punchline, which includes the 'n-word' in the answer.

TMZ claims tit received the video four years ago, but decided not to post it because Bieber admitted that "what he did was stupid." The site goes on to say that Bieber will be addressing the video within the next day.

The video, coincidentally, comes the same week when One Direction was also caught using racist language in a video.
