Paris Hilton has been charged in Los Angeles with drinking and driving.
The millionaire socialite has embarked on a singing career
The hotel heiress-turned-singer was stopped in her car earlier this month. Police said her blood-alcohol level was 0.08%, the minimum to warrant arrest.
At the time she said she had been at a charity event, where she had had just one drink, and was out looking for food after eating nothing all day.
She was fined $390 and put on probation for three years. She will also have to attend an alcohol education scheme.
Shortly after her brief arrest on 7 September, the singer and heiress to the Hilton hotel fortune described the incident during a radio interview.
She denied driving recklessly but she conceded: "Maybe I was speeding a little bit."
If found guilty of driving under the influence, she could face a maximum sentence of six months in jail.
