The Hairspray star has been charged with one count of misdemeanor DUI, and the news is doubly bad for Bynes because District Attorney's officials are seeking a sentencing enhancement because she refused to take either a breathalyzer or a blood test.
If convicted, Bynes faces a maximum of six months behind bars, according to TMZ.com.
The 26 year old's April arrest prompted her father Rick Bynes to speak out in his daughter's defence, insisting the only thing she was guilty of was being ""upset and very emotional"".
Firing back at reports suggesting his daughter had been drinking, Bynes told People.com, ""She was not drunk... She didn't have a single drink that night. My daughter doesn't drink.""
And dad blamed the cop behind the wheel of the police car for the accident, claiming he pulled out in front of his daughter ""as she was turning at the West Hollywood intersection, where she was cited"".
