Beverly Hills Superior Court Judge Elden Fox issued a bench warrant for the actress Monday, requiring her to show in person for the court hearing or face arrest. This is the fourth bench warrant issued in her DUI probation case.
Fox previously warned Lohan that every dirty test for drugs and alcohol would be met with a 30-day jail sentence. Lohan has admitted to failing one test, and reportedly failed at least two, one for cocaine, the other for amphetamines.
Lohan, 24, who previously served 13 days in jail, said on her Twitter page: "This was certainly a setback for me but I am taking responsibility for my actions."
