The 2005 'American Idol' winner performs toe-tapping 'Good Girl', while Julianne Hough, Diego Boneta and Mary J. Blige play a medley of classic rock songs.
A week after visiting "American Idol" on FOX, Carrie Underwood dropped by "Dancing with the Stars" on ABC. The 2005 "Idol" winner appeared on the May 15 elimination night that also featured a live performance by "Rock of Ages" stars.
Underwood sang her lead single "Good Girl" from her latest No. 1 album "Blown Away". Meanwhile, "Rock of Ages" actors Julianne Hough, Diego Boneta and Mary J. Blige delivered a medley of "Juke Box Hero/I Love Rock n Roll" and "Any Way You Want It" with a group of dancers.
Another musical guest who performed before another contestant was sent home was Alanis Morissette. Strumming her guitar, the Canadian singer debuted a brand new single called "Guardian" from her next studio installment "Havoc and Bright Lights".
