If a contestant on American Idol has been on a different reality show and won still be on the Show?

Fox knew this. Its been out since Hollywood week. Apparently the recording contract is not current or she would have been disqualified. Contestant Brent Keith was on Nashville Star. Joanna Pacciti had a multimillion dollar record contract as did Carly Smithson and Michael Johns. The only thing you cant have is a current contract.
