The surprise jailhouse past of a disqualified contestant on American Idol saved two lucky singers from getting voted out of the competition.

Just before the end of Wednesday night's telecast, when host Ryan Seacrest revealed which two contestants had gotten the least amount of votes from viewers, he told them they would both be back next week.

The decision to spare Carmen Rasmusen, a 17-year-old from Utah, and Trenyce, a 22-year-old from Memphis, was made by producers after they disqualified Corey Clark Tuesday when it was revealed he had been arrested last October for beating up his kid sister.

That story was broken by thesmokinggun.com, a Web site that specializes in exposing celebrities' questionable pasts.

Clark had not told producers of his brush with the law, unlike some of the other contestants this season with sordid pasts. Trenyce (aka Lashunda Cobbins) was charged with theft in 1999 and Frenchie Davis posed nude for a Web site geared toward child pornography.

So with Clark gone, Trenyce and Rasmusen were spared because "a decision was made not to eliminate another contestant this week," Seacrest said.
