Siobhan is gone, from American Idol that is. The young lady from New England, who Simon once called, "an odd little thing" couldn't cut it on country week, after Tuesday night's strange version of Shania Twain's"Any Man of Mine."  She was joined in the final two for a heartstopping moment by Casey James, who didn't deserve to be there!  The good thing?  After seeing the Final Six in their Ford commercial, Siobhan may have a future as a movie vampire!  Next week, the final five get mentored by Harry Connick, Jr, singing the songs of Sinatra.  Was disappointed Shania didn't perform last night, although we were treated to pre-taped performances by Lady Antebellum and Sons of Sylvia, with an equally pre-taped intro from Carrie Underwood.  Only Rascal Flatts was live, and as Randy Jackson would say, "it was a little pitchy for me."  The guys sang their huge hit "Unstoppable" and then backed up Latina pop princess Shakira for "Gypsy."  At least she plays a good harmonica.  Check out the "odd little" pairing!
