Can someone please help identify this women?

After her husband was pulled over while being seen weaving down the road, Reese Witherspoon pulled the celebrity go to line "Do you know who I am?" on a not so amused officer. According to the report the exact wording to the state trooper was "Do you know my name? You're about to find out who I am. You're about to be on national news" Miss Witherspoon was promptly arrested for "disorderly conduct" after she refused to stay in the car while her husband was given a field sobriety test. I guess she doesn't remember much from her legally blonde days. "I feel comfortable using legal jargon in everyday life... I object."
