Nobody is havinga go at Katie because they think she is fake. The public are angry because her singing perfomances have been week. She has messed up a number of times with forgetting words to songs yet she is still in the competiton and it's unfair to other acts in the compettion. Everyone is entitled to have one wobbly week. They can be perfect each week. Aiden, Paije and Matt have all had songs that didn't suit them but they bounced back. Mary and Cher suffered on Saturday as well but Mary will be back to her best this week because she knows she has to. The only way Katie can keep her place in the competiton is to put in a faultless performance, no gimmicks or dramas. Just stand there sing and remember the words to the flaming song she is singing. If she ends up in the sing off she goes. Simple as that
