Hold up. Fifty Cent isn't at fault here. Did anyone read what the site said? Taco bell was coming out with their $.69, $.79, $.89 deal thing and wanted Fifty Cent to endorse their campaign. So Taco Bell offered Fifty Cent $10,000 to a charity of his choice if he changed his name for one day (to Sixty-Nine Cent or Seventy-Nine Cent, or Eighty-Nine Cent) and went to a Taco Bell and made an order while rapping. Fifty Cent didn't take the deal, but Taco bell went ahead and put out the idea that Fifty Cent would take up the deal and would be a symbol for their new campaign through marketing and stuff.
So now Fifty Cent loses credibility because of a supposed Taco Bell campaign that he was supposedly a part of, even though he didn't agree to it.
I'd sue Taco Bell too.
