Sharon Osbourne vows to win 'The X Factor'

Sharon Osbourne has vowed that this year's X Factor winner will come from her category.

The 54-year-old took the remaining six hopefuls in the '14-24 girls' category to Los Angeles for the judges' houses stage of the competition, where she admitted that she was confident about her chances.

"It's the perfect thing for me," Sharon explained. "I'm so happy I've got them and they are all here cos they can sing so I want to see a great performance. I'm over the moon - I don't think, I know I have the winner in my category."

The X Factor airs at 6.45pm tonight and Sunday on ITV1.
