MIAMI (CBSMiami/AP) — Another day and another delay in the South Florida trial of pop singer Justin Bieber.

A Miami-Dade County judge postponed a hearing Tuesday morning to determine whether Justin Bieber will be tried on charges of driving under the influence and resisting arrest.

The judge postponed the hearing until 1:30 p.m. Aug. 13 at the request of prosecutors and Bieber’s attorney.

Bieber was arrested Jan. 23 in Miami Beach after what police described as an illegal street race between Bieber, driving a rented Lamborghini, and a Ferrari driven by a friend, R&B singer Khalil Amir Sharieff.

Alcohol breath tests found Bieber’s level below Florida’s 0.02 limit for underage drivers, but urine tests showed the presence of marijuana and the anti-anxiety drug Xanax in his system. Bieber also was charged with driving on an expired license. Sharieff is also charged with DUI.
