It's looking increasingly like 50 Cent really has lost his fortune.

Now he's suing his lawyers to get it back.

In a lawsuit filed today in bankruptcy court, Fif is demanding $75 million from the law firm Garvey Schubert Barer (GSB), claiming they gave him bad legal advice in response to a lawsuit filed against him by Sleek Audio a couple of years ago.

Sleek Audio ended up being awarded $16 million after a judge ruled 50 had stolen their headphone design and the marketing. Now 50 is saying that legal L was the fault of his attorneys:

Among GSB's numerous failures was its inexplicable decision not to call technical and damages experts to rebut expert testimony offered by Sleek — failures relied upon by the arbitrator in crediting Sleek's experts and entering an eight-figure award in Sleek's favor," reads part of 50's complaint.

GSB has issued a statement maintaining that they advised 50 properly:

We understand that Mr. Jackson is disappointed in the outcome of Sleek Audio's arbitration against him. However, Mr. Jackson's complaint against GSB omits a number of relevant facts and misstates a number of others, and we will respond to the allegations in accordance with the court's rules. Our attorneys properly counseled Mr. Jackson and his sophisticated team of financial and operational advisors about the transactions and the arbitrations with Sleek. Unfortunately, the arbitrator in the Sleek case found Mr. Jackson responsible for his actions and the actions of those who performed services for him or his companies. We look forward to demonstrating that our attorneys handled the Sleek matters appropriately in all aspects.
