lindsaymichaelpassport.jpgLindsay is due for her court date tomorrow in which she may be found guilty of not fulfilling her requirements for her 2007 DUI arrest. Meanwhile, reports claim that Lindsay has lost her passport, and most likely, will not make it back from Cannes in time.

Michael Lohan tells X17online exclusively, "She's already making excuses."

Lohan adds, "I don't think the judge is going to buy that she lost her passport. It kind of goes with the territory."

If the judge doesn't accept Lindsay's excuses, there could be a warrant issued for her arrest. That means Lindsay could be taken into custody as soon as she arrives at LAX.
