Lindsay Lohan: Mugshot in Orange Jumpsuit

Lindsay Lohan is officially an inmate at the Century Regional Detention Facility.

The 24-year-old starlet was arrested just after 10 a.m. and booked shortly thereafter. Lindsay was sentenced to 90 days in jail but will likely leave early because of overcrowding.

According to People, Lindsay is neighbors with Alexis Neiers, who is serving six months in jail for involvement in an L.A. robbery ring targeting celebrities – including Lindsay!

FYI: L.A. sheriff spokesman Steve Whitmore tells Us Weekly that Linds will likely only serve “about 14 days”. He adds,” She will be kept away from [the] general population” and has been “extremely cooperative” since entering jail.
