Corey, Corey, Corey. American Idol execs beat viewers to the punch on Monday and gave finalist Corey Clark the hook. The expulsion followed yesterday's TheSmokingGun.com report that revealed the 22-year-old bad boy was arrested last October after a disturbance in his family's Topeka, Kans., home — an incident he failed to report to Idol producers. Fox released a statement saying a background check missed the arrest because the police report misspelled Clark's first name. "We regret the error," the statement went on, "but the only thing we can do is learn from the incident, continue to improve the background-check process and move on." Clark is the third Idol contestant to get the boot for hiding a skeleton in his closet — but probably not the last.
