"American Idol" Viewers Cast Off Siobhan Magnus

From the 33 million registered votes on Tuesday night, Siobhan Magnus received the smallest share from the viewers and was sent home on Wednesday night's elimination episode of "American Idol."

The quirky 20-year-old from Cape Cod, Massachusetts had a habit for belting high notes at the end of all her performances. At first, it wowed the judges, but they soon became less enthused after seeing the same type of execution week after week.

On Tuesday night's episode, Judge Simon Cowell said Magnus sounded like she was giving birth during her rendition of Shania Twain's "Any Man of Mine."

The "Idol" Finale

The results portion of the show began with host Ryan Seacrest divvying up the contestants into three groups of two. The first pair announced was Magnus and Lee Dewyze, then Casey James with Michael "Big Mike" Lynche, followed by Aaron Kelly and Crystal Bowersox.

Going straight to it, Seacrest escorted Magnus across the stage to stand next to James and Lynche, pronouncing them as the bottom three.

Lynche was the first one relieved, but had no shame of being back in the bottom three. "Tonight is different because everyone did well last night," he said.

Once James' name was called and he was declared safe, Magnus managed to keep her head up high and had a smile on her face. She left with style and performed Aretha Franklin's "Think." Naturally she ended the performance with her signature ear-piercing scream.

The Rascall Flatts helped continue with this week's country theme and opened up the show with their performance of "Unstoppable." They made their way back on the stage later on the show for a peculiar duet with Latin pop singer Shakira. Later on, Lady Antebellum sang their chart topping hit "Need You Now."

Cameron Diaz and Antonio Banderas made brief appearances in the beginning to help promote their upcoming movie "Shrek Forever After," which Ryan Seacrest has a brief cameo in.

"Idol" alum Carrie Underwood also paid a visit to her old stomping grounds to introduce her tour mates Sons of Sylvia, who performed "Love Left to Lose."

There is only one female finalist left and the pressure is on full force for Crystal Bowersox to pull through. With only five contestants remaining, the competition is starting to get extra tight.

We'll find out next week who will be capable of reigning supreme when Harry Connick Jr mentors the remaining five as they pick songs from the great Frank Sinatra.
