Actress Amanda Bynes has pleaded not guilty to two counts of hit-and-run.

The Hairspray star was charged with both misdemeanors in Los Angeles earlier this month after allegedly colliding with a police car in April and a second vehicle in August, leaving the scene of the crime each time.

On Thursday, her attorney entered the pleas on behalf of her client in California.

Bynes is due back in court on October 19th and faces up to a year behind bars if convicted, according to TMZ.com.

The 26 year old still faces two counts of driving with a suspended license and one count of driving under the influence. She is due to stand trial on those three charges on October 29th.
