During an interview Thursday on ABC's "Good Morning America," Witherspoon repeatedly apologized for her behavior during the April 19 traffic stop. A police report states that Witherspoon asked a Georgia state trooper, "Do you know my name?" and added, "You're about to find out who I am."
In her first sit-down interview about the arrest, the Oscar-winning actress told ABC's George Stephanopoulos that she had "one too many" glasses of wine, and panicked after she and her husband were pulled over.
"I have no idea what I was saying that night," she said. "I literally panicked. I said all kinds of crazy things. I told them I was pregnant. I'm not pregnant."
Witherspoon, 37, was arrested after the trooper said she wouldn't stay in the car while her husband, Hollywood agent Jim Toth, was given a field sobriety test. Toth was charged with drunken driving and is due in court May 23. Witherspoon faces a May 22 court hearing on the disorderly conduct charge.
Two lawyers for Witherspoon, one in Los Angeles and one in Atlanta, did not immediately return calls from The Associated Press seeking comment Thursday.
"There are so many lessons learned," she said.
"When a police officer tells you to stay in the car, you stay in the car," she said. "I learned that for sure. I learned a lot."
