VIDEO: 'Idol' Boots Teenager Aaron Kelly

All the power of mentor Harry Connick Jr. and Frank Sinatra couldn't save Aaron Kelly from getting the cement-shoe-treatment on American Idol Wednesday night. The 17-year-old Idol hopeful was sent home while the other bottom dweller, Michael Lynche, was saved to sing again next week.

Kelly chose Sinatra's "Fly Me to the Moon" for his final performance simply saying, "I've had a blast."

Lady Gaga stopped by with a performance of her new single "Alejandro," Connick sang his cover of the Beatles' "And I Love Her," off of his new album, and the top five joined in to sing a medley of Connick's other material.

This week's Idol audience (a mere 17 million viewers) was the smallest the show has seen since it debuted in 2002. Next week, the contestants sing songs from the cinema with Jamie Foxx as the guest mentor.
