American Idol results tonight: 4 singers eliminated, Scott MacIntyre and Matt Giraud perform

Four singers will be eliminated on tonight's episode of "American Idol," which airs 8-9 p.m. on Fox. "Idol" alums Scott MacIntyre and Matt Giraud will perform.

MacIntyre and Giraud appeared on the eighth season of "Idol." Giraud placed fifth and McIntyre, who is visually impaired, placed eighth. They'll reportedly duet on Billy Joel's "Tell Her About It" tonight.

It looks like the group song will be "Haven't Met You Yet" by Michael Buble, via Ryan Seacrest's Twitter.

Two men and two women will be sent home tonight, narrowing the pool to this season's top 12 singers. My predictions for elimination: Paige Miles, Katelyn Epperly, Todrick Hall and Lee DeWyze.
