Amanda Bynes has pleaded not guilty to driving under The Influence (DUI).
The 26-year-old actress was arrested in April after accidentally driving into a police car in Hollywood, but denied the charges against her, insisting she can't have been under the influence because she doesn't drink alcohol.
Yesterday (06.06.12), her lawyer entered a not guilty plea in court on her behalf.
The plea came a day after the 'Hairspray' star tweeted to urge US President Barack Obama to intervene in the case - and have the police officer who arrested her fired.
She wrote: ''Hey Barack Obama... I don't drink. Please fire the cop who arrested me. I also don't hit and run. The end.''
Prosecutors are seeking a sentencing enhancement in the case because the actress reportedly refused to submit to either a breathalyser or a blood test at the scene of the accident.
If convicted, she faces up to six months in prison.
A pretrial court date has been set for July 18.
