Emma Willis hosts the final night of live knockout rounds, and it is time for Gavin Rossdale's team to sing for a place in the quarter-final. Gavin and the other coaches - Jennifer Hudson, Sir Tom Jones and will.i.am - all take their places in the in... (more)famous red chairs, but it is now down to the public to decide who stays and who goes home. Only three acts can go through and the two acts with the highest number of public votes get a place, leaving Gavin to save one other act from his team. The three acts that make it through will be one step closer to the chance of winning a recording contract with Polydor Records. will.i.am gives a very special performance live in the studio.
