The rapper known as 50 Cent is suing his former lawyers for $75 million, accusing them of malpractice and not adequately representing him in business matters, including an intellectual property case involving his line of headphones.

Curtis James Jackson III, whose stage name is 50 Cent, filed a lawsuit in U.S. Bankruptcy Court in Connecticut against Garvey Schubert Barer, a law firm which has offices in New York. Jackson, a Connecticut resident, is a Grammy-award winning rap music artist, investor and entrepreneur. He filed for relief under Chapter 11 of the U.S. Bankruptcy code in July of this year. He owns a mansion in Farmington, which is currently for sale.
