LOS ANGELES -- Former Three's Company star Joyce DeWitt has been sentenced to three years probation stemming from her DUI arrest in El Segundo last year.

The 61-year-old actress entered a no contest plea Thursday through her attorney.

In addition to probation, DeWitt was also ordered to undergo a nine-month alcohol program and pay a $510 fine, plus penalty assessments, according to Jane Robison of the Los Angeles County District Attorney's Office.

DeWitt was arrested on July 4th after driving around a barricade at Pine Avenue and Sierra Street near the city's annual fireworks show, El Segundo police Sgt. Dan Kim said.

Witnesses said DeWitt pulled up in a black sports car, parked, and staggered toward a police officer standing in uniform next to his motorcycle. Officers say DeWitt appeared to be intoxicated, so they administered a field sobriety test.

She was charged with two misdemeanor counts including driving under the influence, and driving while having a 0.08% or higher blood alcohol level. Officials say DeWitt's blood alcohol was .15% at the time of the incident -- which is almost twice the legal limit.

As a result of her plea, a second misdemeanor DUI count was dismissed.

DeWitt played Janet Wood on the popular 1970's hit TV show "Three's Company."
