Jackie Evancho goes 'Over the Rainbow' at Oprah's farewell

We've heard Jackie Evancho sing numerous times now, but we still have a hard time getting our heads around the 11-year-old's vocal talents.

Jackie, the runner-up on "America's Got Talent" last year, was part of Oprah Winfrey's "Farewell Spectacular" on Monday (May 23) singing the prelude to "Over the Rainbow." She was dwarfed physically by the massive stage at Chicago's United Center, but her voice had no trouble filling the arena.

She shared the stage on Monday's show with the likes of Tom Cruise (who you can see for a second at the start of the video below), Beyonce, Halle Berry and Josh Groban, among others. Oprah's farewell continues Tuesday, and her final daytime show airs Wednesday.
