It was her adrenaline that really made the performance perfect.
I understand that if she's not your cup of tea then you probably won't understand, but as a fan I have to defend her because I think she's talented. She performs as if she's already a superstar. She can sing, dance and is generally a natural-born performer.
She never came on with a sob story; in fact she was barely highlighted at the beginning. She's performed many different songs that previous acts would never be able to get away with. She's just a breath of fresh air on The X Factor franchise.
I love Fleur and hope she's successful after the show.
