Aaron Billington refused to comment outside court
A Suffolk chef has admitted causing an estimated £30,000 damage to a £1m Ferrari belonging to Jamiroquai frontman Jay Kay.
Aaron Billington, 21, of Aldeburgh, admitted causing criminal damage to the Ferrari Enzo outside a hotel in the town where the singer had been staying.
Lowestoft Magistrates' Court heard Billington committed the crime in a "moment of madness" early on Tuesday.
He said he became upset by "offensive" remarks the singer made.
Robert Barnwell, prosecuting, said: "During the evening, witnesses in the case had been socialising with staff from the hotel.
"One witness describes the defendant as being arrogant towards Mr Kay.
"He later admitted in interview to drinking a bottle of vodka and being drunk prior to the incident.
"Another describes him as being more aggressive as the evening went on. They also say that Mr Kay appeared to not want to speak to him."
The driver's side window was smashed in the incident
Mr Barnwell said Billington was seen "using swinging motions with his arms" as he threw stones at the car, shattering the windscreen and smashing the driver's side window.
Damien Moore, mitigating, said Billington told him he had been "sparked into a fit of anger" by the singer on Monday night - and caused the damage in the early hours of the following day.
"On this particular evening it was his night off," said Mr Moore.
"He was socialising with people, which included the complainant and others, and he says that, as the evening progressed, the complainant began making some comments which Mr Billington found to be deeply offensive.
"And he says that, because of the comments that were being made, he felt that there was an element of provocation which sparked him, essentially, into a fit of anger."
Mr Moore said Billington accepted he acted "totally inappropriately".
June Hutson, chairman of the magistrates, said the case would be committed to Ipswich Crown Court for sentence at a later date.
Billington was released on bail.
