Little Mix & Fleur East slay together on X Factor UK final...

Little Mix and Fleur East's 'Black Magic/Sax' mash-up was really fierce and they executed a fab five-part harmony!

This performance was just as engaging as the JLS/Alexandra Burke mash-up a few years ago. The choreography was fun, hot and really in sync. Fleur was a great fit, and if anyone were to leave the group, she would make the perfect replacement. Even now she could be added as a fifth member!
