Lindsay Lohan was ordered to appear in court Thursday because she reportedly failed an alcohol test. Sources told TMZ Lohan was tested for alcohol twice last week, and reportedly tested positive for alcohol on one of the tests. She did, however, pass the drug tests. Sources said the Probation Department will ask an L.A. County Superior Court judge to revoke Lohan’s house arrest and instead put her in jail. Lohan reportedly also had parties while under house arrest. She is serving a 35-day house arrest sentence after entering a plea bargain for stealing a necklace.
