This wee girl is so brave!
Not only did she have the courage to get up and belt out a song in front of hundreds of people, but she bravely sang it acapella when Simon Cowell requested her too, and didn't seem too fazed when he asked her to leave the stage and come back later that day with a brand new song.
On her third song, she blew the judges away - even earning a standing ovation from Simon Cowell!
