NEW YORK (Reuters Life!) - Rocker Amanda Overmyer got the boot from "American Idol"'s huge fan base on Wednesday, leaving 10 finalists singing their way to possible victory in the hit TV talent show's seventh season.

The vote by millions of "Idol's" viewers for their favorite singers left Overmyer, Kristy Lee Cook and Carly Smithson as an all-female bottom three, with Overmyer coming in last.

Overmyer, 23, from Mulberry, Indiana, had performed "Back in the USSR" during a second consecutive week of Beatles-themed singing.

"Idol"'s judges concurred with viewers' choice of the lowest voter-getters. Asked by host Ryan Seacrest whether "America got it right," Simon Cowell confirmed, "Two weeks running, yes."

Overmyer, who stood out with her raucous performances, dramatically streaked hair and edgy style, was philosophical in defeat, telling Seacrest, "It's been a run," adding that "number 11 out of all them people was more than I could ever expect."

Seacrest lauded her as "one of the most fearless contestants we have ever had."

Following her elimination, Overmyer will not join the "American Idol" tour, which is reserved for the top 10 contenders.

"American Idol" pits singers against one another in a months-long competition. Past winners such as Kelly Clarkson and Carrie Underwood have gone on to music stardom. The weekly show draws nearly 30 million viewers, making it the most-watched program on U.S. television.

The other remaining finalists include David Archuleta, 17; Jason Castro, 20; David Cook, 25; Chikezie Eze, 22; Michael Johns, 29; Ramiele Malubay, 20; and Brooke White, 24.

Also performing on Wednesday night's show was season five contestant Kelly Pickler.

This season's mentors were also announced and included Dolly Parton, Mariah Carey, Neil Diamond and Andrew Lloyd Webber.
