"This weekend&amp;#039;s X Factor quarter-final will have two themes: Guilty Pleasures and Heroes. It was previously reported by This Morning&amp;#039;s Jeff Brazier that the final five acts would be singing Motown classics, but that has proved incorrect. All five acts - Janet Devlin, Marcus Collins, Amelia Lily, Little Mix and Misha Bryan - will be performing two tracks on Saturday (November 26) for the first time in the series.      Little Mix have emerged as the bookmakers&amp;#039; new favourites over the past week, following a fall in support from punters for Lily and Collins.  The girl group&amp;#039;s backing has soared following their En Vogue cover on last weekend&amp;#039;s Movies night. The X Factor quarter-final airs on Saturday (November 26) at 8pm on ITV1. Sunday&amp;#039;s X Factor results show will feature performances from Xtra Factor host Olly Murs and &amp;#039;Price Tag&amp;#039; popstar Jessie J. &amp;gt; Coldplay, Michael Buble, Jessie J for &amp;#039;X Factor&amp;#039; final duets Look through a gallery of behind-the-scenes images from the X Factor charity video shoot below: "^^<http://www.w3.org/2001/XMLSchema#string>
