In UK Avril is the biggest and most current out of the 3 so whoever would've duetted with her would've won, hopefully US is different 'cos of what I've seen of TXFUS Melanie needs to win. Saying that though...this is X FACTOR USA, its meant to draw in current names, if in UK we can get beyonce, michael buble, christina agueria, rihanna etc shouldn't USA have got even bigger names since, its the USA! Plus a bigger budget?!
