Could music producer Scott Storch's cash flow be running low? One Florida insider told Page Six Storch's credit cards were recently declined at a Miami club. "He's had to pay cash for everything," said the source. In 2006, Rolling Stone reported that Storch , who has worked with 50 Cent, Fat Joe, Christina Aguilera and Beyoncé, was worth $70 million. But by August 2007, Forbes had that number down to $17 million, and we've reported on Storch's panache for covering lady friends like Lindsay Lohan in expensive diamond jewelry.
