Lindsay Lohan has just been sued for $5 Million

Lindsay Lohan has just been sued for $5 million she doesn't have ... all because of her highly-publicized drug problem.

D.N.A.M. Apparel Industries -- a clothing manufacturer -- just filed the countersuit against Lindsay in response to Lindsay's lawsuit against the company.

In her lawsuit, Lindsay says she struck a business deal with D.N.A.M. in 2009 allowing them to manufacture clothes for her "6126" clothing line -- but D.N.A.M. stiffed her on a massive licensing fee. Lindsay wants $1.1 million in damages.


But D.N.A.M. is now coming back at Lindsay for nearly five times that amount, insisting SHE'S the reason their business deal fell apart.
 
D.N.A.M. claims Lindsay's "drug-addled image" destroyed 6126's reputation, and rendered the clothing line completely unsellable. They also say it invested millions in 6126 for nothing -- and now it's suing for breach of contract and fraud, demanding at least $5 million in damages.

And Oh! FYI... Lindsay's currently back in rehab yet again.
