(CBS News) -- Actress Amanda Bynes was officially charged by Los Angeles prosecutors on Tuesday with driving under the influence. The charges stem from an incident roughly two months ago when authorities say she grazed a sheriff's patrol car in an early morning accident.

The actress took to Twitter to start pleading her case; she even tried to have President Barack Obama hear her out.

"Hey @BarackObama...I don't drink,"tweetedthe 26-year-old Bynes. "Please fire the cop who arrested me. I also don't hit and run. The end."

Bynes was arrestedon suspicion of DUI in April while she was driving her black BMW at 3 a.m., when police say she ended up colliding with a vehicle.

TMZreports that this was not the actress' first run-in with the law. She was pulled over on March 7 for allegedly talking on her cell phone, and she reportedly drove away from the scene before the ticket was written. She was not arrested and later returned to the police station to sign her ticket.
