Is This Bieber's Most Offensive Move Yet?

TMZ has a video of Justin Bieber from earlier this year that prompted the gossip site to call the singer "an oblivious, self-important little twit." What could Bieber possibly have done to deserve such an assessment from the oh-so-morally-upright TMZ? Exited a New York nightclub through a restaurant kitchen ... where he stopped to pee into a mop bucket. Then he stopped again, to spray a photo of Bill Clinton with cleaner while declaring, "F--- Bill Clinton!" His entourage seems to think the whole thing is hilarious, and TMZ hypothesizes they were all drunk.

Bieber managed to offend at least three other times this week (four, if you count his latest shirtless self-portrait): On Tuesday night, hockey fans were outraged when a Chicago Blackhawks rep tweeted a picture of Bieber touching the Stanley Cup, Mashable reports. And in the wee hours on Sunday, Bieber basically asked his Twitter followers to engage in piracy, Perez Hilton reports. He tweeted, "Who has a video of the ufc fight tonight? Send it to me," referring to a fight from Saturday night. The UFC boss responded, recommending Bieber wait for Pay Per View. Last but not least, on Sunday night, he was more than three hours late to his Iowa concert, Perez Hilton reports. (More Justin Bieber stories.)
