Now this is the video we've been waiting for!

A clip surfaced last month of Reese Witherspoon being taken in to an Atlanta police station, but now the video of her mouthing off to her arresting officer has hit the web, and we've never seen this side of the Oscar winner!

As you know, the former Legally Blonde star was arrested for disorderly conduct on April 19 after her husband Jim Toth was pulled over on a DUI traffic stop. Witherspoon disobeyed the officer and stepped out of her car, and when he began to cuff her, she flipped out. "Do you know my name sir?" Reese barked. When the officer said he didn't need to know, Reese added, "You're about to find out who I am!" Toth stayed calm during the drama, but after Reese was cuffed he told the cop, "I'm sorry, I had nothing to do with that." (Yesterday Witherspoon plead no contest to physical obstruction of another.)

Witherspoon went on Good Morning America for her first interview since the arrest on Thursday morning, and she apologized again and admitted that she said a number of crazy things, including that she was pregnant! "I know better. It's just unacceptable," she said.
