Justin Bieber DUI hearing rescheduled

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

The judge on Tuesday postponed the hearing until 1:30 p.m. on 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 and a friend.

Alcohol breath tests found Bieber's level below the 0.02 limit for underage drivers, but urine tests showed the presence of marijuana and an anti-anxiety drug. Bieber also was charged with driving on an expired license.

It is unknown whether Bieber will attend next week's hearing.

The 20-year-old pop star has been working on new material with Australian singer Cody Simpson. Bieber retweeted a photo Monday of the pair in the studio together:
