Lindsay Lohan: I'm Going to Trial!

Lindsay Lohan told a confidant minutes ago after leaving the courtroom ... she will not cop a plea in her grand theft case, and she's going to trial ... TMZ has learned.


Lindsay said bluntly, "I didn't steal" and made it clear she will not accept a plea bargain that involves ANY jail time.

Judge Schwartz made it clear ... Lindsay will do jail time if she she cops a plea.
