O'Neal, 48, has a long history of substance abuse, but she insisted she had kicked her habit once and for all after her 2008 arrest for cocaine possession. She pleaded guilty to the misdemeanor charge and was ordered to complete two sessions in a drug treatment program.
The daughter of actor Ryan O'Neal even served as her embattled half-brother Redmond's sober buddy in 2010 to help him get clean after multiple drug arrests. In October 2011, he was spared jail and ordered to return to a treatment center after he confessed to using drugs while in rehab.
