Bynes was not in court, but had her lawyer enter the plea on her behalf, TMZ reports. The "What I Like About You" star was formally charged with a DUI following her arrest April 6 after colliding with a police car in West Hollywood. She refused, however, to take a breathalyzer or blood test.

If convicted, Bynes could face a maximum of 6 months in jail and a minimum of 48 hours in jail.

The actress reached out to President Barack Obama on Tuesday for help in her case. "Hey Barack Obama... I don't drink," she tweeted. "Please fire the cop who arrested me. I also don't hit and run. The end."

Bynes was also allegedly involved in a hit-and-run accident in Hollywood a month after her DUI arrest. On May 27 she tweeted, "I can't help but laugh at all of you writing fake stories about me. I was not in any hit and runs. I don't drink so the DUI is false."
