She Dances Like Any Young Ballerina.. Until She Opens Her Mouth And SHOCKS The Harshest Judge.

At first, Hollie Steel is just your average 10-year-old who dreams of being a ballerina when she grows up — and it doesn't take long for Simon Cowell, the harshest judge of the bunch, to start rolling his eyes and ushering her off the stage. But within seconds, Hollie opens her mouth and transforms from an adorable dancer to a phenomenal singer. And Simon's expression completely changes.

Hollie's rendition of "I Could Have Danced All Night" from "My Fair Lady" left all the judges stunned. I certainly didn't see that coming, and neither did they!
