No matter who you are, don’t pull the “Do you know who I am?” routine with cops. Always backfires. Even for Reese Witherspoon.

The Oscar winner and her agent husband Jim Toth were both arrested early Friday in Atlanta, reports Variety — he charged with DUI, and she with disorderly conduct, after she allegedly quarreled with the officer who pulled them over. Variety cites a police report saying that while Toth, 42, was undergoing a sobriety test, the actress hung out the car window and told the officer she doubted he was really a policeman. While her husband was submitting to arrest, Witherspoon, 37, refused orders to stay in the car and asked the officer, “Do you know my name?”; he said no, and she countered with, “You’re about to find out who I am.” Sigh. No. Never do this!

The couple, in Atlanta for a movie shoot, were briefly held before being released on bond. Wed two years ago, they have an infant son together.

Update, 12:30 am Monday: Witherspoon issued an apology late Sunday, after walking the red carpet for the NYC premiere of her new movie, “Mud,” where she did not speak with reporters. “I clearly had one drink too many and I am deeply embarrassed about the things I said,” she said in her statement, reports AP. “It was definitely a scary situation and I was frightened for my husband, but that is no excuse. I was disrespectful to the officer who was just doing his job. I have nothing but respect for the police and I’m very sorry for my behavior.” (Mug shot, above: City of Atlanta Department of Corrections via AP)
