Siobhan Magnus Voted off "American Idol"

NEW YORK (Reuters) - The music of country singer Shania Twain spelled Siobhan Magnus' downfall on Wednesday, leaving only one woman among the five remaining finalists on "American Idol."

After 33 million votes Magnus, a tattooed, punk-styled singer from Cape Cod, Massachusetts, was eliminated from the hit television show's ninth-season despite the judges' overall praise for her rendition of "Any Man of Mine."

Magnus showed very little emotion at being voted off the singing contest, saying she had done her best before launching a farewell performance of "Think."

The other two singers at the bottom of this week's pack were Casey James and Michael Lynche. All of the performers had landed in the bottom three in past weeks, and Lynche was actually voted off by fans before being spared by the judges, who used their once-per-season save to keep him singing.

The other remaining finalists are teenager Aaron Kelly, Lee Dewyze and Crystal Bowersox, this season's last woman singing and a strong contender to win, despite uncharacteristically tepid feedback from the judges this week.

Wednesday's live broadcast included several musical performances, including Rascal Flatts singing "Unstoppable" before they teamed up with Colombian pop singer Shakira, debuting her new single "Gypsy."

Sons of Sylvia, introduced by season No. 4 winner Carrie Underwood, sang "Love Left to Lose" while Lady Antebellum took to the stage for "Need You Now."

Cameron Diaz and Antonio Banderas also made a brief appearance to promote their new movie "Shrek Forever After."

Harry Connick Jr. will next mentor the finalists for a songs-of-Sinatra themed week.

The finale airs in May, when the next "Idol" winner lands a recording contract and enviable media exposure. Past champions such as Kelly Clarkson and Underwood have achieved major stardom, but last year's winner Kris Allen has been overshadowed by runner-up, glam-pop singer Adam Lambert.
