I've never seen it, american x-factor, but I think they've really messed her around. It wouldn't do the americans any harm to occasionally be exposed to an accent. They just can't cope with accents. We are all used to Scottish, Irish, London, welsh, Australian and so on and so on.
I hope this isn't pegged as 'casual anti-americanism' but I think it's ridiculous tbh. I'm sure that if she was speaking with an american audience in mind they would have understood her.....!!!!
