One singer from the top 12 will go home on tonight's episode of "American Idol," which airs 9-10 p.m. on Fox.
The show will include appearances by Orianthi ("According to You"). Ke$ha ("Tik Tok") and season seven "Idol" champ David Cook.
The 12 finalists on Tuesday performed songs by the Rolling Stones. Crystal Bowersox and Siobhan Magnus led the pack. My prediction for tonight's bottom three: Tim Urban, Lacey Brown and Andrew Garcia.
