Here's a lesson in what not to do when you're skipping the court date that will decide whether you go to jail for violating probation: Pose beside a tray of cocaine, at a no-pants party in Cannes. LiLo did it.

Or, so it seems from this gallery of photos TMZ posted today, depicting Lindsay partying with friends in Cannes on the nights leading up to the probation hearing she missed in L.A. because her passport was "stolen" and she couldn't get a new one or fly back in time. These are also the days she could have spent completing the remaining three alcohol education classes she was supposed to do. And the stuff on that mirror tray sure looks like cocaine. Unless someone emptied a bunch of pixie sticks right there?
