Amanda Bynes has pleaded no contest to alcohol-related reckless driving after she clipped a Los Angeles County sheriff's patrol car.

According to district attorney's spokeswoman Jane Robison, She's The Man star Amanda entered the plea on Monday through her lawyer.

The former teen star was sentenced to three years of probation and three months of attending alcohol education classes.

Amanda was arrested in April 2012 on suspicion of drunken driving after the cruiser was hit in West Hollywood.

The 27-year-old actress is already on probation for driving with a suspended license. She received psychiatric treatment last year after authorities said she started a fire in the driveway of a Ventura County home.

Amanda was also ordered to get counselling after she allegedly threw a bong out of a Manhattan window last year.
