Lindsay Lohan -- Model Ex-Con

Lindsay Lohan met up with her new best friend ... her probation officer -- which is no small feat considering she was spotted at Chateau Marmont last night.


Lindsay was at the courthouse in Santa Monica this morning, where she checked in with her probation officer ... on time.

Baby steps.
