Justin Bieber Attacks A Paparazzo While Out With Selena! (10 PICS)

Losing his cool: Justin Bieber is wanted for questioning by Los Angeles County Sheriff's investigators after a paparazzo complained of being roughed up by the pop star at a shopping center

Oh! Baby, baby, baby NO!

Seems Justin Bieber is in a lot of trouble this Memorial Day weekend.

Yesterday afternoon, The Biebs decided to do a little shopping with his girlfriend Selena Gomez at an outdoor mall in Calabasas. While the exact details of the fight have yet to be released, SEVERAL sources have confirmed that Justin got into a physical altercation with a paparazzo, who was trying to snap the winning pic of the darling pair.

One witness told sources that the photog blocked Justin's car in so that he and Selena couldn't leave, thus giving him a better opportunity to snap a photo. Justin got out of his car, got into the guy's face and a fight broke out.

Cops were called to the scene, allegedly by the paparazzo, but by that time, Justin was already long gone. We're told law enforcement officials will be looking into the matter and it is likely that Justin could be facing a misdemeanor battery charge.

Tsk, tsk Justin! You know better than this! Violence is never the answer. We're just glad neither you or this guy got seriously hurt.
