Justin Bieber will reportedly settle his driving under the influence (DUI) case with a plea bargain.

The 20-year-old singer is to plead guilty to reckless driving after he was arrested in January for allegedly drag racing down the streets of Miami in the early hours of the morning.

The 'Baby' hitmaker was also charged with resisting arrested and driving without a valid licence, but it is believed those charges will be dropped if he pleads guilty, pays a fine and attends anger management classes.

A source told TMZ.com: ''Bieber will plead guilty to reckless driving and the other charges will be dismissed. He'll pay a fine and attend anger management classes. He will not be placed on probation.''

It is believed the settlement has taken so long because prosecutors allegedly wanted the troubled star to produce, star in and pay for an anti-drug PSA as well as attend a drugs and alcohol education course.

However, Justin's lawyers allegedly resisted as they felt it was inappropriate as the hunk was reportedly neither drag racing or drunk on the night he was arrested in Miami.

He did, however, test positive to marijuana.

Meanwhile, Justin's rapper friend Khalil Amir Sharieff, who was also arrested for DUI, will allegedly use the same plea but will not have to attend anger management classes.

The deal is expected to be entered in court in a few weeks.
