The Blind Auditions enter their fifth week, as Will.i.am, Jennifer Hudson, Olly Murs and Tom Jones reassemble to assess the singing skills of more would-be stars. Emma Willis ushers the contestants on-stage where, yet again, the coaches must decide whether they would like to back each performer based on the power of their voice, rather than their appearance. Only once a coach decides to support the singer are they permitted to turn their chair around. (thetvdb.com)
