Drugs, alcohol and out-of-control partying have been a central part of rehab-graduate Mischa Barton's life for at least two years, sources
close to the actress tell RadarOnline.com.
Mischa was placed on an involuntary psychiatric hold Thursday by Los Angeles police and taken to Cedars-Sinai Medical Center. RadarOnline.com obtained exclusive eyewitness details of the star out partying in recent months.
Her drug "secret" became public in 2007 when she was photographed smoking what appear to be a joint in her car, as you can see by the RadarOnline.com photo.
In January of this year she was at the Troubadour club in Los Angeles to see the group the Cold War Kids. "She's obsessed with the band," said a source who saw her there. The source said Mischa was again smoking dope and was romantically pursuing the group's lead singer.
She was spotted at Chateau Marmont with the Cold War Kids in February and eyewitnesses told RadarOnline.com, "She tried to hook up with the lead singer but was turned down and ended up coming on to the drummer. She was a mess. Totally out of it."
Months before, at the end of 2008, multiple sources told RadarOnline.com they saw Mischa partying in LA several nights a week. On Dec. 27, 2007, she was pulled over and arrested for DUI and marijuana possession, and later released on $10,000 bail.
