Lindsay Lohan served only 4.5 hours in jail from the 30-day sentence

Even she was due to serve a 30 days sentence, Lindsay Lohan has been released from jail after just 4.5 hours in custody.

Lindsay Lohan enjoyed a last supper with friends before she checked into the Century Regional Detention Facility in Lynwood, CA , last night just before 9:00 p.m. to begin serving her 30-day jail sentence.

LiLo didn’t need to pack an overnight bag though as she was released at approximately 1:30 a.m. and headed back to her rented home having spent almost as much time out eating sushi earlier in the evening as she spent behind bars.

Lindsay Lohan early release is thought to be due to overcrowding in prison.

The actress must now complete the remaining 53 days of her community service, including at least 12 days a month at the county morgue.

The sentence also requires Lindsay Lohan to undergo 18 psychotherapy sessions and appear monthly at court hearings between December 2011 and March 2012.

Judge Stephanie Sautner also said Lindsay Lohan can no longer leave the country and needs the permission of her new “no-nonsense” probation officer to travel outside California.

Lindsay Lohan, 25, will have to serve 423 hours at the county morgue, where for nearly two weeks she has been scrubbing floors, cleaning toilets and washing dirty sheets.

After jailing Lindsay Lohan, Judge Stephanie Sautner said: “You are not to get house arrest or early release, except for that required by the law.“

The sentence marked LiLo’s fifth jail term since her arrest in 2007 for drunken driving.

After her sentencing, Los Angeles County Sheriff spokesman, Steve Whitmore said: “It’s possible she could be booked in and booked out the same day.

“It depends on the fluctuations of the day, what’s going on in the jail.”

Lindsay Lohan was set to begin her 30 day jail sentence after being found guilty of violating her probation and was ordered to check in to the Lynwood Regional Correctional Facility before November 9 but found time to tie up some loose ends first.

On Saturday night Lindsay Lohan and friends went to Wabi-Sabi Sushi and Asian restaurant for a low key dinner.

LiLo seemed in high spirits as she laughed in the bar, which is just a stone’s throw from her home in the trendy enclave.

She has had a busy few days and reportedly stripped for Playboy on Wednesday.

But it is said the shoot was the second for Lindsay Lohan after Hugh Hefner decided he wasn’t happy with the first set of photos and hired a new photographer.

Sources told RadarOnline: “Lindsay was told that the Playboy executives wanted to go another direction with her shoot so they asked her to come back for a second time.

“There is never a guarantee that everyone will like the photos or that they will be of high enough quality to use for the cover, but Playboy wanted to make sure that Lindsay’s pictures were exactly what they wanted.”

On Wednesday, Lindsay Lohan waived her rights at her probation violation hearing at the Los Angeles Superior Court Airport Branch and admitted the violation.

Judge Stephanie Sautner ordered her to surrender to the jail by Wednesday.

Lindsay Lohan was not immediately put behind bars because the judge decided to allow her time to complete her nude photo shoot for Playboy, according to TMZ.

Lindsay Lohan’s lawyer, Shawn Holley, is understood to have told the judge in chambers that her client had a $1million contract with Hugh Hefner’s publication.

As well as serving the jail time the star must continue her community service at the Los Angeles county morgue. But TMZ reported that Lindsay Lohan may serve just minutes behind bars.

A source within the Sheriff’s Department told TMZ that if someone receives a misdemeanor sentence of 90 days or less, they are routinely processed in and then released.
