As always TMZ is on the celebrity probation grind, and Lindsay Lohan seems to be their favorite target. Late yesterday afternoon the gossip website reported that Lindsay Lohan, who is currently on house arrest, tested positive for alcohol and has been ordered to appear in court and face Judge Stephanie Sautner tomorrow at 10am.

Sources tell TMZ

the L.A. County Probation Department will ask Judge Stephanie Sautner to yank her out of house arrest and throw her in L.A. County Jail.

And, we're told, members of the D.A.'s office -- will make an appearance as well, to lower the boom on Lindsay.  The D.A. is still handling the DUI probation part of Lindsay's criminal saga.  The L.A. City Attorney is handling the necklace case.

The Probation Department is pissed off because they tried to force Lindsay to take two tests in May but Lindsay's lawyer, Shawn Holley, refused to make Lindsay submit, claiming it wasn't part of her probation.  Turns out it was, so Lindsay subsequently took the two tests, one of which she failed.

The Probation Department isn't thrilled that Lindsay is throwing house parties and BBQs while under house arrest, not to mention she has been shooting commercials in her home for extra cash while locked down. As extreme as this all sounds, my bet is on another 'slap on the wrist' for Ms. Lohan, as usual.
