No charges have been officially brought against her following the Nov. 30 incident, but the celebrity news website said she was arrested and booked, and prosecutors now have the case.
Police officers said they pulled LeBrock over after they spotted her speeding and driving erratically.
Investigators said they noticed signs of alcohol impairment while questioning her, so they gave her a field sobriety test, which she didn't pass, TMZ reported.
LeBrock, 53, had memorable roles in the films "The Woman in Red" and "Weird Science."
