George Michael has been warned he could face jail after he admitted crashing his Range Rover while under the influence of cannabis.
The 47-year-old pop star appeared amid heavy security at Highbury Corner Magistrates' Court after he was arrested last month.
He pleaded guilty to driving while unfit through drugs and possessing two cannabis cigarettes when he was held in Hampstead, north-west London, in the early hours of July 4.
The court heard the former Wham! frontman was found slumped at the wheel of his car after a resident dialled 999 to report a vehicle had ploughed into a branch of Snappy Snaps.
Police who banged on the window to rouse him suspected he was under the influence of something after they found him "spaced out" and with no memory of what had happened.
George was found carrying two cannabis cigarettes and tests on a sample of his blood revealed he had chemicals linked to the drug in his system.
District Judge Robin McPhee banned the music star from driving and said he could be jailed when he returns to the court next month to be sentenced. Mr McPhee said: "I make it clear all options, in respect of sentencing, remain open, including powers to imprison.
"It is a serious matter. Your driving was extremely poor and there was an accident. There is also your conviction from three years ago."
When arrested, Michael admitted smoking a "small quantity" of cannabis about 10pm the previous evening and said he also took a newly-prescribed sedative to help him sleep.
In court, the Faith singer spoke only to plead guilty and confirm his name, age and address during the short hearing. He will be sentenced at the same court on September 14.
