E! reports They's Company star, Joyce DeWitt, was arrested by SoCal cops for apparently a little too much prefireworks celebrating on the Fourth.

DeWitt was busted Saturday around 4:30 p.m. on suspicion of DUI, El Segundo Police Sgt. Dean Howard tells E! News.

"An officer saw DeWitt drive a vehicle past a barricade intended to control vehicular traffic near a park," says Howard. "As the officer spoke with DeWitt, he observed signs and symptoms of alcohol intoxication."

DeWitt, 60, whiffed a series of field sobriety test and was hauled away to the station for booking.
