Babyshambles singer Pete Doherty has been fined £300 and disqualified from driving for two months.
Pete Doherty was arrested in November last year
The 27-year-old admitted two charges of driving without insurance or a licence at Thames Magistrates Court in London.
District Judge Jane McIvor warned the singer that he faces jail if he drives without a licence again.
The rock star was arrested in November 2006 by officers who spotted him driving his Jaguar erratically near his east London home.
He was fined £200 for driving without insurance, £100 for driving without a driving licence, plus £55 costs.
Mr Doherty's defence counsel said the singer was eligible for a licence, but had not applied for one after passing his driving test.
Fans in gallery
Sean Curran added: "Mr Doherty accepts that he was driving with no licence and insurance.
"He had left the task of getting an insurance policy in the hands of one of his managers, who hadn't done so."
Two other driving-related charges were withdrawn.
Several fans watched from the gallery as Mr Doherty admitted the charges. He also
spoke to give an address in St John's Wood, north London.
Two people who were arrested alongside Mr Doherty were also in court.
Michelle Breeze, 30, a retail manager from Streatham, south London, was charged with two counts of possession of heroin. Her case was adjourned until 6 March.
Peter Wolfe, 38, a songwriter from Maidstone, Kent, was fined £300 and ordered to pay £55 costs for possession of cocaine.
