The X Factor Semi Final was never going to be tame, with this week's mash-up theme of Motown vs. The Song to Get You into The Final. With semi-finalists Mischa B, Marcus Collins and Amelia-Lily having their performances universally praised, it proved a rocky night for Little Mix - who were criticised for shakey vocals in their renditions of If I were a Boy and Set Me Free. But it was Mischa who was finally given her marching orders in a nail-biting showdown. Catch up with all the fashion and twitter action from the show, below.
