Lohan was freed from her latest jail stint on Sept. 24. After one judge ordered her held without bail until a court hearing next month, a second judge cleared the way for her release on $300,000 bail on several conditions -- including that she be fitted with an alcohol-monitoring bracelet within 24 hours of her release and refrain from drinking alcohol or possessing controlled substances.
Lohan's return to jail came after her admission that she failed a court-mandated drug test.
"Regrettably, I did in fact fail my most recent drug test and if I am asked, I am prepared to appear before Judge Fox next week as a result," Lohan wrote on her Twitter account on Sept. 18. "I am so thankful for the support of my fans, loved ones and immediate family, who understand that i am trying hard, but also that I am a work in progress, just as anyone else. I am keeping my faith, and I am hopeful....Thank you all!!!"
The stint behind bars was Lohan's third round in jail for a three-year-old drug and DUI case that followed two highly publicized 2007 arrests. Lohan left a rehab program at UCLA Medical Center on Aug. 24 after 23 days of treatment. Earlier in August, she was released from jail after serving just 13 days of a 90 day sentence for violating her probation.
At an August hearing, judge Fox ordered Lohan to go to weekly psychotherapy and behavioral therapy sessions, in addition to 12-step dependency program meetings and mandatory drug tests. Fox said if Lohan was found to be in violation of the terms of her probation, she could go to jail again for 30 days.
