Rapper 50 Cent has sued his former business partner Sleek Audio LLC because of an unpaid $250,000 loan that he had lent to the company back in 2010, this according to The Miami Herald.  Fifty had initially partnered with Sleek Audio to develop his wireless headphones Sleek By 50.  He claims that once Sleek Audio reached $750,000 in revenue they would begin to pay back the loan.  

After trying to get the money back in March of this year, he terminated the contract with Sleek Audio in May. He is not only trying to get back the initial $250,000 but is also seeking $61,429 in interest.
