According to TMZ, the troubled actress has been ordered to appear at the Los Angeles Superior Court on Thursday (June 23) after registering positive for booze.

With the failed test said to have taken place last week, a TMZ insider tells that the L.A. County Probation Department is pushing for Lohan to be immediately sent to L.A. County Jail.

With Judge Stephanie Sautner set to preside over the matter, Lindsay’s alleged house arrest/probation violation case will be heard during a hearing slated to being at 10AM PT.
