LiLo Flunks Alcohol Test, Ordered Back to Court

Another day, another failed substance abuse test for Lindsay Lohan: Yes, she's headed to court again this morning, after testing positive for alcohol last week. Sources tell TMZ LiLo was tested twice, including once after she threw a rooftop barbecue, and tested positive one of the times. They add that the Probation Department will ask the judge to toss Lohan, currently under house arrest, back in jail for violating probation. As for that rooftop party? The department is reportedly not happy about that particular house arrest activity, either. Click here for more. (More Lindsay Lohan stories.)
