An attorney for Paris Hilton entered not guilty pleas on her behalf Tuesday to charges of misdemeanor driving under the influence.
Hilton, 25, wasn't required to appear in court.
She was arrested in Hollywood in September. Police said they saw her "driving erratically" and pulled her over for a field sobriety test.
The judge set a pretrial hearing for Jan. 23 and said the trial must begin by Feb. 23.
If convicted as a first-time offender, Hilton would likely face a fine, enrollment in an alcohol-rehabilitation program and a possible license suspension, according to prosecutors.
Hilton has starred with sometime-friend Nicole Richie in the reality TV show "The Simple Life."
