Justin Bieber’s hearing to determine whether the singer will be tried on charges of driving under the influence and resisting arrest, has been postponed.

The Miami-Dade County judge postponed the hearing until 1.30pm on August 13 at the request of prosecutors and Bieber’s lawyer. Bieber was arrested Janusary 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 was also charged with driving on an expired license. It’s unknown whether Bieber will attend next week’s hearing. He is currently partying in Ibiza.

Justin Bieber was arrested in Florida on January 23 2014 on suspicion of driving under the influence and drag racing in a residential area of Miami Beach. He was allegedly in a rented yellow Lamborghini at the time. The singer told cops he had taken anti-depressents, drank a beer and was smoking marijuana all day, according to police sources. The pop star was incoherent, had his hands in his pockets, was driving without a valid license and resisted arrest without violence, Miami Beach Police Chief Raymond Martinex told the Miami Herald at the time.

The 20-year-old says he wants to take full responsibility for his behaviour and looks to rebuild his shattered reputation. Bieber - who was arrested earlier this year driving offences - admits this is ‘one of the hardest things I’ve ever dealt with.’

He insists he needs to ‘step up and down what I did’ as he fears family, friends and fans may never forgive him. ‘Facing my mistakes from years ago has been one of the hardest things I’ve ever dealt with,’ he said. Bieber continued: ‘But I feel now that I need to take responsibility for those mistakes and not let them linger.’ He told The Sun: ‘I just hope that the next 14-year-old kid who doesn’t understand the power of these words does not make the same mistakes I made years ago. ‘At the end of the day I just need to step up and own what I did. Once again, I’m sorry for all those I have let down and offended.’
