Lindsay Lohan has reportedly tested positive for alcohol.
The Mean Girls star apparently tested positive for alcohol on one of two tests administered last week, according to TMZ.
Lohan who is currently under house arrest for a parole violation, has been ordered to appear in front of Judge Stephanie Sautner at the Los Angeles Superior County Court on Thursday morning at 10am.
TMZ also reported that prosecutors are expected to ask for the actress to be removed from house arrest and sent to jail.
The 24-year-old star is said to have tested negative for drugs in both instances.
