TMZ has obtained Lindsay Lohan's brand new mug shot -- in which she's dressed in an orange jumpsuit and cracking a smirk.
The photo was taken moments after Lindsay arrived at the Lynwood Correctional Facility to begin her 90-day jail sentence.
According to her booking sheet, Lindsay checked in at 5'6" and weighs 118 lbs.
As we previously reported, Lindsay will only serve 23 days because of overcrowding.
