Mystery in Lindsay Lohan Case

7/20/2010 4:08 AM PDT
Lindsay Lohan's lawyer had a confidential meeting with Judge Marsha Revel this afternoon, and the D.A. didn't even know about it ... TMZ has learned.

We're told Shapiro breezed into court at around 4:00 PM and went directly into chambers.

We're assuming Shapiro is making plans for Lindsay's surrender tomorrow morning.
