She wasn't even a competitor on the show, but Susan Boyle arguably stole the finale of "America's Got Talent" Wednesday night when she made her US television singing debut. Boyle sang a version of the Rolling Stones' "Wild Horses" and spoke briefly of her hospitalization.

Boyle told cameras in a piece that aired before her song that, "I've never felt so tired. I look back at it now and it was a necessity because I was tired," but she's upbeat now. "I used to be a spectator looking out at the world, but now I'm part of that world."

The Scottish singer became a YouTube sensation after an appearance earlier this year on "Britain's Got Talent," on which she sang "I Dreamed a Dream"

Her album is in stores November 24.
