Each of Lohan's arrests were followed by trips to rehab, but Meyers noted that "did not play a part in our agreement."
Lohan's legal problems come on the heels of two other high-profile celebrity DUI cases that resulted in jail time. Paris Hilton served 23 days behind bars after she was found guilty of driving on a suspended license while on probation for an alcohol-related reckless-driving case. Nicole Richie was ordered to serve four days in jail stemming from a December DUI arrest. She checked in and out of the women's jail in Lynwood on Thursday after serving less than two hours, said Michael Bialys, Los Angeles DUI lawyer.
