Justin Bieber Puts Fan's iPhone Down His Pants (VIDEO)

Justin Bieber, the 19-year-old Canadian crooner, recently surprised fans who threw things at him onstage during a performance at the Prudential Center in Newark, N.J.

"Do you guys want me to keep performing or what? Refrain means DON'T throw things on stage," Bieber told his audience after a bandana was thrown on stage.

However, someone decided to ignore Bieber's warning and throw a cell phone on stage at the singer. The singer reacted by putting the phone down his pants.

"I said don't throw stuff on stage and this is what they throw - a phone on stage," Bieber told his audience. "I mean, I do need a new iPhone."

Bieber has been the subject of intense media scrutiny recently. However, his mother Pattie Mallette insists that the singer has been unfairly judged. Mallette recently appeared on Bravo TV's "Watch What Happens Live" where she admitted that she knew her son was not always on his best behavior.

"(I'm) not naïve to think that my child is perfect and making all the best decisions of his life," Mallette told Bravo host Andy Cohen last month.

Still Mallette stood up for her 19-year-old son amid recent media scrutiny.

"I definitely think he's getting a bad rap ... He knows what I disagree with, and he knows all the things that I'm really proud of him for, too," Mallette told Cohen. "I mean, people don't talk about all the great things he does every day."

Mallette pointed out that her son meets with children from the Make-A-Wish charity foundation before each of his shows.

Recently, Bieber was reportedly kicked out of a Chicago bar for being underage and allegedly urinated in a bucket. Bieber has also been making headlines for his alleged reckless driving habits, aggressive behavior and alleged marijuana use for months.

However, Mallette has insisted that she does not want to speak too deeply into her son's behavior, saying: "He wants me to continue to respect his boundaries and my relationship with him. Everybody has their own opinion and everybody wants to sensationalise everything," Mallette said in The Advertiser.
