It's Boot Camp! And the remaining contestants are put through their paces, having to perform once again for the judges in a series of singing challenges. First, contestants must race to the Wall of Songs and choose a song which they will have to perform together in groups of four. If they succeed in impressing Simon Cowell, Nicole Scherzinger, Sharon Osbourne and Louis Walsh, the contestants will earn a coveted place at the next stage of Boot Camp, the Arena Auditions. Dermot O'Leary, will be on hand to guide viewers through all the Boot Camp action as well as providing hopefuls with those much-needed ‘Dermot hugs'.
