As Early Show national correspondent Hattie Kauffman reports, The Material Girl reported to court to fulfill her civic duty -- in a sweatshirt and sunglasses.
The mega-pop star was among some 60 potential jurors called for a simple driving-under-the-influence case.
Lawyers had mixed feelings about the prospect of Madonna on a jury.
"Sometimes," says attorney Richard Falk, "a very famous actor or actress or celebrity, I would imagine, would cause a distraction to the proceedings."
"I would think," says legal eagle Bill Reich, "she would be a fine juror."
She wasn't picked for the panel.
Madonna spent the day sequestered, busy on her blackberry -- and she changed during the lunch break into a sleek black pant suit.
Sources close to the singer tell The Early Show that the jury room was infiltrated by paparazzi and became a circus. They say a defense lawyer complained that she was a distraction, leading to her dismissal. They also claim a court officer accused Madonna of disturbing the peace -- just by being present.
However, court officials say there weren't any problems, and it was just business as usual.
We are, Kauffman pointed out, entitled to a jury of our peers, and you'd hardly think Madonna is a peer.
But, it was the Beverly Hills courthouse, where celebrities sometimes go on trial, and where other celebs have been called to serve -- celebs such as Jennifer Lopez, Brad Pitt, and even Calif. Gov. Arnold Schwarzenegger.
"Remember," says CBS News legal analyst Trent Copeland, "we're in Beverly Hills, California, a place that's highly-populated by celebrities. So, it's not unusual to have a celebrity called into court as either a defendant or to sit on a jury pool."
Madonna spokeswoman Liz Rosenberg tells CBS News, "She was happy to serve her civic duty, even though she didn't get onto a case."
Apparently, Kauffman notes, Madonna, whose many hits include "Express Yourself," knows jury duty is as American as -- the freedom of expression.
