ON 'AMERICAN IDOL'

"An independent spirit, laser focus, incredible work ethic," host Ryan Seacrest said of Magnus after announcing her elimination, as the studio audience in Hollywood's Kodak Theatre stood and saluted her "Idol" run. "I know you did this for your sisters…what impact do you think it's made on both you and your sisters being a part of this show?"

"Hopefully a big one," said the 19-year-old Massachusetts native. "I did my best and I hope that I was able to show them what we're all capable of."

'American Idol' Recap: Big Mike Shine on Shania Twain Night

Magnus was the last contestant to perform on Tuesday's Shania Twain-themed episode, making her elimination all the more suprising (contestants who sing last are typically perceived as the week's favorite). Known for her eccentric style and high-pitched notes, Magnus brought back her trademark "scream" on Tuesday while singing Twain's hit, "Any Man of Mine." Her spunky performance was mostly praised by the judges, with the exception of Simon Cowell, who compared her high note to the sound of "a woman giving birth."

Magnus was joined in the bottom three on Wednesday by Casey James and Michael Lynche, who had also received mostly positive feedback for their Twain covers.

For her farewell number, Magnus revisited her memorable performance of Aretha Franklin's "Think" and then walked over to the judges table and hugged Cowell, Kara DioGuardi and Ellen DeGeneres. "I'm going to miss you," said Cowell, while DioGuardi said, "You did great tonight." "I'll see you tomorrow on my show," said DeGeneres. Randy Jackson offered his vote of confidence for Magnus' future as a recording artist. "Keep being yourself," he told her. "You learned how to be an artist on this show and face all the adversity and everything. I think that you've got an amazing career in front of you. Do it. Be about it."

Wednesday's results show also featured country stars Rascal Flatts performing "Unstoppable," and later joining Latin star Shakira for a performance of her current single, "Gypsy." Lady Antebellum performed the title track from its chart-topping album, "Need You Now," while Carrie Underwood introduced Sons of Sylvia, who are opening for the former "Idol" winner on her current "Play On" tour.

The remaining five "Idol" contestants will tackle Frank Sinatra's catalog next Tuesday (May 4).
