Same Difference want to help children

X Factor stars Same Difference are hoping that they can be positive role models for children.

Brother and sister act Sean and Sarah Smith, who finished in third place in last night's final, revealed that they will not give up on their dream of chart success.

"We want to help kids in a good way," Sean told the Daily Star Sunday. "Drink and drugs are seen as the cool things at the moment but we have proved you don't have to be like that.

"People say we are too nice and too smiley but we wouldn't have it any other way. I certainly think there is room in the charts for an act like us."
