Lindsay Lohan Rehires Shawn Holley!

Lindsay Lohan is in a heap of trouble ... and guess who's back to dig her out of the hole? That would be the lawyer she fired ... Shawn Holley.

Multiple sources connected to the case tell TMZ ... Lindsay BEGGED Holley to return as her lawyer after Thursday's hearing. We're told Lindsay was angry at her lawyer Du Jour, Mark Heller, for recommending Morningside Recovery to fulfill her 90-day rehab obligation. After we posted a story that Morningside had its license revoked, Lindsay decided she didn't want to go there.

So Lindsay and her team spent the better part of Thursday convincing Holley to come back on board. And, we've learned, clearly a glutton for punishment, Holley agreed.

Sources tell us Holley, who did not return our calls, has already been in touch with prosecutors and is trying to keep them from seeking an arrest warrant.

TMZ broke the story ... Lindsay never entered Morningside -- which the judge required her to do -- and if she's not there first thing this morning, prosecutors are going to court for a warrant. But we've learned Holley is trying to get prosecutors to agree to a rehab facility other than Morningside ... and if they do she's promised Lindsay will be there.

As for Heller, as far as we know, he's in the dark that he's the latest victim of Lindsay's ax.

And one final thing. We broke the story ... Lindsay still owes Shawn $150,000 for all the stuff she did before she got the chop. See, sometimes the client is the a-hole.
