George Michael has been jailed for eight weeks after he admitted crashing his Range Rover while under the influence of cannabis.
The 47-year-old star, whose real name is Georgios Panayiotou, was found slumped at the wheel of his car after it ploughed into a branch of Snappy Snaps in the UK.
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.
The Wham! star was found to be carrying two cannabis cigarettes and tests on a sample of his blood showed he had chemicals linked to the drug in his system.
Michael, who has a previous conviction for the same offence, admitted driving while unfit through drugs and possessing two cannabis cigarettes when he appeared at London's Highbury Corner Magistrates' Court last month.
He was jailed today when he appeared at the same court for sentencing.
Michael sighed as District Judge John Perkins sentenced him. He was told he would serve four weeks in prison and spend the remainder on licence.
Michael was also banned from driving for five years and was ordered to pay a £1,250 fine, £100 costs and a £15 victim surcharge.
The court heard Michael was also convicted of driving while unfit through drugs after he was found collapsed in his Mercedes in October 2006. He was banned from driving for two years and sentenced to 100 hours of community service, to be carried out within 12 months, when he was sentenced for that offence in June 2007 at Brent Magistrates' Court, north London.
The judge today said he had taken a "dangerous and unpredictable mix" of prescription drugs and cannabis.
