Michael Buble wows the X Factor

The Canadian singer was a surprise guest at the X Factor finals on Saturday night

Michael performed one of his songs from his Xmas album to a standing ovation. It was the highlight of a  tense night where X factor finalists Little Mix, Marcus Collins and Amelia Lily found out who went  through to Sunday night's final.                                

Sadly Amelia didn't make the cut despite a strong rendition of Ike and Tina Turner's classic 'River Deep Mountain High'.
