The winner of the competition--who will be awarded a recording contract--will be announced on the May 21 episode of "American Idol"

The show's eight other finalists were: Joshua Gracin of Oceanside, Calif.; Kimberley Locke of Nashville, Tenn.; Trenyce of Memphis, Tenn.; Carmen Rasmusen of Bountiful, Utah; Kimberly Caldwell of Katy, Texas; Rickey Smith of Keene, Texas; Julia DeMato of Brookfield, Conn., and Charles Grigsby of Oberlin, Ohio.

This year's "American Idol" contestants recently debuted at No. 1 on the Billboard Hot 100 Singles Sales Chart with their cover of Lee Greenwood's "God Bless the U.S.A." Last month, RCA issued "American Idol Season 2: All Time Classic Love Songs," which includes the "God Bless the U.S.A." single.

Winner Kelly Clarkson and the other top-10 finalists from last year's edition of "American Idol" opened a tour of U.S. theaters and arenas last October.
