Carrie Underwood To Help Pick Song For 'American Idol' Finale

The star-studded lineup for the two-night season 10 "American Idol" finale is starting to come into view, and it will feature a former "Idol" champ whose career is a model for finalists Scotty McCreery and Lauren Alaina.

The two country-singing teens will take the stage on Tuesday night (May 24) to sing three songs each — one their favorite from this season, another chosen by "Idol" producers and the third picked by one of their personal music idols. According to USA Today, those heroes will be Country Music Hall of Famer George Strait for Scotty and season four "Idol" champ Carrie Underwood for Lauren.

Underwood, who recently became the most successful "Idol" winner in history, is also the first and only country champion from the show.

Wednesday night's finale will feature an appearance by U2's Bono and the Edge, who will take the stage alongside the lead actor of the troubled Broadway musical "Spider-Man Turn Off the Dark," which features songs written by the iconic rock duo. The season-ending show also will include season seven "Idol" winner David Cook, who will singing this season's elimination song, Simple Minds' "Don't You (Forget About Me)," as well as a performance from judge Steven Tyler.

In addition, bearded season 10 growler Casey Abrams will take the stage with "Kung Fu Panda 2" funnyman Jack Black.
