American Idol followers - the time has finally come. The time when contestants from previous seasons come back to remind us about what we may have already forgotten.

Later this week, Allison Iraheta - arguably one of the more memorable singers from recent years - will get her chance to sing for us once again. Season 8’s fourth place-finisher will perform “Scars,” a song off her debut album Just Like You. That CD - released December 1 - also includes a song (“No One Else”) co-written by Pink, Greg Wells and Idol‘s Kara DioGuardi.

Kris Allen, last year’s champ, will also be a part of Thursday’s results show. Allen will be sharing footage from his recent trip to Haiti in addition to singing for the audience.
