Casey Abrams and Haley Reinhart no Sonny and Cher on 'American Idol'

Haley Reinhart and Casey Abrams are singing "I Feel the Earth Move" next on "American Idol."

Man, Casey jumps in totally off-key. Not seeing any synergy here. They're sharing the stage but not much chemistry, and the song doesn't really lend itself to a duet. They spend a lot of it standing at opposite ends of the stage, actually.

Steven Tyler teases Casey, asks him "how much in love with Haley are you?" He loved it, and that's the only judge who speaks.
