According to Entertainment Weekly’s Michael Slezak (Here):
Allison Iraheta, fourth-place finisher from season 8 of American Idol, will perform her new single “Scars” during the show’s Thursday-night telecast (8 p.m. ET on Fox). A live performance by the red-headed rocker should provide momentary respite for the four season 9 semifinalists (two men, two women) who’ll get the boot during the course of the hour-long telecast. “Scars, ” written by Toby Gad and Alyssa James, and produced by Gad, is a ballad from Iraheta’s 2009 debut Just Like You.
The episode will also feature Kris Allen performing, and sharing his experiences from his recent trip to Haiti…
Really happy to see Allison is getting a second single. “Scars” is a good one–really shows off her vocal chops in a way that “Friday I’ll Be Over U” did not.
