George Michael has pleaded guilty in a London court to driving under the influence of cannabis when he crashed his car into a shop last month.
The 47-year-old singer also admitted possessing cannabis cigarettes.
A scrum of photographers met Michael as he arrived at Highbury Corner Magistrates' Court dressed in a black suit over a black jumper.
In court, he spoke only to give his plea and confirm his real name of Georgios Panayiotou.
District Judge Robin McPhee gave the singer an interim six-month driving ban and said he would be sentenced on September 14 after the court considers his case.
He will remain on bail until that date.
I make it clear the options in respect of sentence remain open, including the power to imprison, the judge said.
It is a serious matter. Your driving was extremely poor and there was an accident.
There is also a conviction from three years ago.
In the latest incident, Michael was arrested after his Range Rover crashed into a photography shop in north London in the early hours of July 4.
The court heard how police found the singer slumped at the wheel with the engine still running.
Officers roused him and said he appeared spaced out.
In June 2007, Michael was given a two-year driving ban after pleading guilty to driving while unfit.
On that occasion, he claimed he was tired and had been taking prescription drugs.
The singer, who first found fame in 1980s pop group Wham!, has fought a long battle with drugs.
