“Most of the time it's the parents who recognise me. They try to tell their kids, 'Look, it's Giselle,' and I say, 'No, no, no, don't ruin this for them,' because I'm usually standing there with my hair sideways and no make-up on. And the kid is saying, 'That is not Giselle. No way. That is some worn-out girl who really needs a bath.'”
