Lindsay Lohan released from jail after just 4 hours

Lindsay Lohan has been released from jail after serving just four-and-a half hours of a 30-day sentence.

The 25-year-old actress handed herself over to authorities at the Century Regional Detention Facility in Lynwood, California, at 8:48pm last night but due to overcrowding she was released at 1.30am this morning.

The star was sentenced to prison last week after admitting she had violated the terms of her probation in relation to a 2007 DUI (driving under the influence) case.

Lindsay acknowledged in court that she had failed to show up at community service appointments at a women's shelter in Los Angeles.

Superior Court Judge Stephanie Saunter told Lindsay - who attended the Los Angeles Superior Court Airport branch in a navy polka dot dress and Giuseppe Zanotti high heels - she will now have to perform all of her community service at a morgue and complete 19 psycho-therapy sessions by March 29, 2012.

If she completes them all, her probation will be over and the rest of the sentence will be stayed indefinitely.

If she fails to do so, she will have to serve the remainder of the 270 days of her sentence.

On Thursday, Lindsay is due to re-shoot her pictures for Playboy magazine.

The troubled star - who was paid around $1 million to pose naked in the pages of Hugh Hefner's men's magazine - has to strip off for the cameras again after bosses decided they weren't satisfied with the first set of shots.

A source previously said: "Lindsay was told the Playboy executives wanted to go in another direction with her shoot so they asked her to come back for a second time.

"The first pictures of Lindsay weren't exactly what they wanted so they have a new theme that they want to shoot."
