The troubled actress - who was on 24.09.10 sentenced to four weeks in prison for violating the terms of her probation - is now free after posting her $300,000 bail, which was granted after her attorney Shawn Chapman Holley launched an appeal claiming she was unlawfully denied it.
Los Angeles Sheriff`s spokesman Steve Whitmore said: "She`s been very cooperative - always has been - the first time, and then the last time. Let`s hope this is the last time."
Judge Patricia Schnegg overturned Judge Elden Fox`s initial ruling she must stay behind bars until her next court appearance on October 22.
Although Lindsay is a free woman, the judge ruled she must be fitted with a SCRAM alcohol-monitoring device within 24 hours if released.
Lindsay - who served just 13 days of a 90-day jail term in July for violating the probation terms of a 2007 conviction for driving under influence (DUI) - was sent back to prison after she failed two court-ordered drug tests, testing positive for cocaine and amphetamine abuse.
It was widely believed Judge Fox would send the 24-year-old star back to rehab, rather than prison.
However, he made his decision without hearing arguments from lawyers on either side.
Lindsay was said to look "shocked" and glanced at her attorney upon hearing the ruling, before being escorted out of the courtroom in handcuffs.
Lindsay spent just 22 days of a 90-day court-ordered rehab stint following her release from prison in August.
