Reese Witherspoon has opened up about her behaviour towards the police officer who charged her with disorderly conduct two weeks ago, calling it “one of those nights.”

“We went out to a restaurant in Atlanta, and we had one too many glasses of wine,” Witherspoon, 37, said in an interview with Good Morning America yesterday.

“We thought we were fine to drive,” she said, looking humbled “and we were absolutely not, and we are so sorry and just so embarrassed. We know better and we shouldn’t have done that.”

Her husband, agent Jim Toth, was charged with DUI after being pulled over and being tested with a blood alcohol limit of 3 times the legal amount.

The police report noted that the Oscar winner and mother of three did not follow the officer’s orders asking her to stay in the car, and that she spoke in abusive language to him.

“I was so disrespectful to him,” she admitted in the interview. “I have police officers in my family. I work with police officers every day. I know better. It’s just unacceptable.”

“I have no idea what I was saying. That night I saw him arresting my husband, and I panicked. I said all kinds of crazy things,” she continued. “I said I was pregnant – I’m not pregnant. I said crazy things. I had no idea what I was talking about.”

Her biggest lesson from the incident? “When a police officer tells you to stay in a car, you stay in a car.”

But she says owning up to her two older children, Ava, 13, and Deacon, nine, was “the hardest part about it. When you make a mistake, you take responsibility, and we are taking responsibility, and we are doing everything within our power to make it right.

“We made a mistake, and it was something that will absolutely never happen again,” Witherspoon admitted.
