Singer George Michael had a cocktail of drugs in his system when police found him slumped over the wheel of his car last year, a London court heard yesterday.
The former Wham! star was arrested in his Mercedes in October after officers responded to complaints that the car was blocking a north London intersection.
Prosecutor Andrew Torrington told Brent magistrates' court that tests showed the 43-year-old singer had a therapeutic quantity of an anti-depressant and traces of the so called 'date rape' drug GHB in his body at the time of his arrest.
Cannabis was also found in Michael's blood, Mr Torrington revealed, although he did not argue that it was the cause of the star's intoxication.
Michael's lawyer maintained that a sleeping drug was the most likely cause of the singer's condition.
The star, whose real name is George Panayitou, pleaded guilty to driving while unfit under the influence of drugs on May 8th.
Michael, who claims that his condition was caused by "tiredness and prescribed drugs", told judge Katherine Marshall at the time that he had done something "very stupid" which he was "very ashamed" of.
He is now due to be sentenced on June 8th, the day before he performs at the new Wembley Stadium as part of his European tour.
The singer, who was not present at yesterday's hearing, issued a statement afterwards.
"I am delighted that at today's hearing the court accepted that the proper approach to my case is that which I have always maintained, in that I was unfit through a combination of tiredness and prescribed drugs, and that I will be sentenced on this basis," Michael said.
The charge which the star has pleaded guilty to carries a maximum penalty of six months in jail, but commentators say that he is likely to receive a lesser sentence given his guilty plea and the fact it is his first conviction.
