Celeb Witnesses Went Unnoticed Before Grand Jury

We're usually better than this, but TMZ has learned some of the alleged celebrity victims in the Burglar Bunch case walked right through the front door of the criminal courthouse in downtown L.A. to testify before the Grand Jury, and no one noticed.

TMZ just broke the story ... defendant Nick Prugo has been indicted by the Grand Jury. We've now learned other defendants in the case have also been indicted and the judge will receive the indictments later this AM. Sources say Courtney Ames and Roy Lopez Jr. are among those indicted.

We don't know specifically which celebs testified, but the roster is impressive -- Orlando Bloom, Lindsay Lohan, Paris Hilton, Rachel Bilson, Megan Fox, Brian Austin Green, Audrina Patridge and Ashley Tisdale.
