Justin Bieber -- FIGHTS Miami Beach Charges ... Pleads NOT GUILTY

Breaking News

Justin Bieber
will FIGHT charges in Miami Beach that he resisted arrest, was driving under the influence and driving with an expired license ... he has pled not guilty.

In Miami Beach, being arrested for a misdemeanor is equivalent to being charged.  Justin's arraignment is scheduled for Valentine's Day, but his lawyer, Mark Shapiro, has entered a written not guilty plea.

Bieber will still be arraigned but is not required to be present in court.

Law enforcement sources tell us ... they could still add charges before the arraignment.

TMZ broke the story ... prosecutors are going to have problems because Justin's blood alcohol level was imperceptible -- .014 -- yet they claim he reeked of booze.  Cops also say he was drag racing yet the GPS readout shows he was not.

As we reported ... Justin will be charged in Toronto with assaulting a limo driver.  And he's also being investigated for egging his neighbor's house, and that could be filed as a felony.

Justin Bieber -- keeping lawyers gainfully employed.
