American Idol iTunes theme week results air 9 p.m. tonight

One singer goes home on tonight's episode of "American Idol," which airs 9 p.m. on Fox. David Cook and Lady Gaga will reportedly perform on the one-hour show.

Tuesday, the nine finalists performed songs from the iTunes charts. Kris Allen led the pack with his contemporary take on "Ain't No Sunshine." Adam Lambert and Danny Gokey also delivered standout performances.

Other contestants struggled. The Ledger's "Idol" blog named Lil Rounds and Scott MacIntyre the worst performers of the night.
