Paula Abdul's nightmare ain't over yet. Corey Clark's lawyer said Tuesday that the former American Idol contestant has "explicit" and "incriminating" evidence that will prove he had an affair with Abdul. Although his attorney stresses that Clark has no plans to make the evidence public, he told The Associated Press that his client would "fully cooperate with any governmental agency that launches an investigation stemming from his claims." Translation: The bidding for the blue-stained dress starts at $500. Do I hear $550?
