When a 12-Year-Old Girl Opened Her Mouth to Sing, the Britain's Got Talent Judges Were Not Expecting This!

A lot of acts walk across the Britain's Got Talent stage over the course of a season, but every once in a while, there's a talent that blows absolutely everyone — the judges (even Simon Cowell), the audience, and the viewers at home — completely away. Beau Dermott is one of those talents, and a very unexpected one at that. At just 12 years old, Beau told the judges she would be singing Wicked's "Defying Gravity" — a song that even the most talented adult singers find challenging — and she totally nailed it, taking everyone's breath away.

Watch — and try not to get emotional — as this talented little lady shows off her beautiful voice.
