Lohan's Porsche rear-ended a truck on Pacific Coast Highway on June 8, but she denied she was driving. She entered a no-contest plea in March and agreed to enter rehab, spend 18 months in psychotherapy and serve 30 days of community service.
Lohan spent several months in 2010 at Betty Ford, where an employee accused her of assault. Prosecutors declined to charge Lohan.
