Lindsay Lohan -- I Paid My Lawyer Shawn Holley!!!

Lindsay Lohan is no longer a deadbeat ... at least in the lawyer dept., because we've learned she's paid Shawn Holley the fortune she's owed her in legal fees.

TMZ broke the story ... when Lindsay fired Shawn back in January, LiLo owed the lawyer $150,000. As we reported ... when Shawn agreed to come back last month, she demanded assurance she'd get paid, and we've now learned that's exactly what happened.

Sources connected with Lindsay tell us ... the actress has made good on the debt and is earmarking money for future services so she doesn't fall behind again.

Good move Holley. It worked!
