Justin Bieber just can’t stop courting controversy.

In a June 1 report in The Sun, the “Boyfriend” singer, 20— who counts actor Jaden Smith, 15, as one of his closest friends and pop superstar Usher , 35, as a longtime mentor— was caught red-handed on video telling a tasteless racist joke to pals.

“Why are black people afraid of chainsaws?” he asks an unidentified female friend in the tape, believed to have been taken when the star was 17.
