Lindsay Lohan -- Jailbound?

Lindsay Lohan may become a wanted woman today -- but not by a Hollywood studio -- by a pissed off judge.

Lindsay is scheduled to be arraigned this AM in an L.A. court for allegedly lying to cops after her car crash last June. TMZ broke the story ... she fired her lawyer, Shawn Holley Monday and is switching to New York lawyer Mark Heller.

Now here's the problem ... Sources tell us Heller will NOT be in court, and even if he showed up he couldn't appear on her behalf because he needs to follow a procedure to go before a California judge (since he's not licensed to practice in CA) and he hasn't done that.

We're told Shawn Holley will be in court, but only to tell the judge Lindsay gave her the boot.

So without any lawyers to enter a plea on her behalf, Lindsay's only option is for her to appear and enter the plea herself. But we're told she won't be in court.

So the judge has scheduled a hearing -- ordering Lindsay to either appear or have a lawyer appear on her behalf, and that order is about to be violated. When that happens, judges routinely issue a bench warrant for the defendant's arrest.
