Ke$ha to Ex-Manager -- I Don't Owe You Squat!

8/5/2010 6:30 AM PDT
Ke$ha is firing back at her former management -- claiming she doesn't owe the New York firm a dime from all the cash she raked in with her 2010 album ... because she fired them in 2008.

Kesha Lawsuit
According to new docs filed in New York State Court -- obtained by TMZ -- Ke$ha claims she acted within her legal rights when she fired DAS Communications ... despite their lawsuit that states otherwise.

DAS is demanding more than $14 million in damages ... but Ke$ha wants their suit tossed out of court -- and a source close to the singer claims the whole thing is "a sad cynical attempt by a manager trying to profit off his former client's recent successes."

In other words, blah blah blah.
